英文原文Multi-purpose aggregate machine-tool timeRegarding the multi-purpose aggregate machine-tools, in the industrial field has many names to describe it, like “the multitasking installment”, “the multi-purpose engine beds”, “the multi-procedure production system” and so on, it may be called the processing domain truly the nova, may reduce the cost, the simplified disposition, and has maintained in the US territory produces. Inthe past only then used the duty which many machine operations could complete, now may concentrate to an engine bed on processes completes.As a result of market demand's unceasing change, the product life cycle is reducing unceasingly, today's market more intense demand multitasking installment concept. Carries out the fine profit management when the entire production environment, compared to having not concentrated the components processing to a machine on completes a finer profit.Some tradition's manufacturing industry manufacturer thought that the multi-purpose aggregate machine-tools are too complex,very difficult to find the appropriate operators also the difficult problem innovates on the spot on the insufficiency for the metal working Basic principle and in the Production workshop related new engine bed use solution aspect training.Intuition type technical controlThe equipment use “carries off the quantity of heat” the type design, has different material which the lathe bed, the steeliness straight line rolling guide, on the steeliness revolving tool box saddle, the equipment uses, all these combine make an engine bed together. These with the thermal conductivity, the volume expansion are related. All different size's thing can by the different speed growth.As a result of this reason, needs to make the hot friendly engine bed, with the aim of knowing gives off heat the weak point in where, can compensate through the reasonable engine bed design. The part is the entire journey movement. The engine bed glide produces rubs and transform hotly. The machining produces the hot filings fall to the different place, the refrigerant can mix in the entire process in which. Will present the different temperature province continually on the cutting tool, will therefore also have many things to have the influence to the thermostability. The cutting tool technology turned the multi-purpose aggregate machine-tools has had the milling and cutting power “the versatile machine”.According to the material introduced that the most remarkable characteristic is in these engine bed whole has the intuition. The anti-collision preservation technology was already mature, in certain circumstances, even if uses the manual operation pattern, can also avoid the occurrence which collides. Because the control software has the very good intuition, the user operation friendly degree unceasingly is also enhancing. Believe the multi-purpose aggregate machine-tools by its survivability world-wide in the more different processing scenes.The off-line programming optimization and the NC automatic control system's formation already made this technology to be easier to accept, when therefore uses the procedure when the engine bed, does not need to spend many time tune-up procedure and confirmed that some part does not have the question. If components need to provide the high and low two revolving tool box saddle simultaneously to carry on the rough machining, in this kind of situation the programming is quite difficult, because it needs two revolving tool box saddles also to feed. The AdMac system may realize tool rest's automatic programming which simultaneously feeds to these, and can cause the correct main axle speed, the correct feed rate and so on all parameters to realize the synchronization.Okuma Corporation's collision avoidance system design based on actual processing operating mode anti-collision simulation, therefore, if the operator has installed the wrong cutting tool or has established the wrong parameter, the control system will examine and prevents the engine bed to enter the processing condition. Through cooperates with the Siemens, INDEX Corporation may provide the 3D pattern now “the hypothesized engine bed”, has custom-made according to some specific model's engine bed. The result indicated that the simulation processes not only the fabricated parts and the actual end product is similar, is the one-to-one copy simply.The intuition type control interface, the simulation as well as other software technique are progressive, the more Production workshops have opened wide the front door to the multi-purpose aggregate machine-tools, but if does not have the corresponding knowledge to train and to solve the question creativity, the manufacturer is also very difficult to realize and the full use advanced engine bed flexibility aspect superiority. The work which does to the machine are more, the machine will be more complex, also needs to have the stronger skill person correspondingly to be able to operate it.If machinist past one day operated 3 engine beds, then he has this kind of multi-purpose engine bed now, might produce more components. More importantly, he may draw support from software's help to cause the production efficiency to be higher, regarding transformation processing components preparation, may also establish the processing craft plan. Because the replacement components need to lower 3 main axles, therefore before replacing the components, the workshop should process as far as possible many components. Regarding the multi-purpose engine beds, the transformation components speed is quick, the production batch of time interval is shorter, the stock is lower, the production efficiency is higher. Can use multi-purpose engine bed's some workshops fully, very quick will discover the post function the unification. Now, a workshop may only use an operator, an adjuster and a programming teacher, in the future these 3 work definitely may do by a person.In the traditional post description the machinist will transit becomes one to adjust engineer, if this engineer the familiar components processing programming, that were also more ideal. Regarding such transformation, training has been simple, so long as trains 1 individual line, but is not 3individuals. Looking from the long views, this will provide to the people the higher post degree of satisfaction. When adjusts engineer to be responsible to process the programming, and pays attention to the components processing personally time the entire process, he completely has become this components control. In addition, but should also makes more effort in the cutting tool choice and the programming aspect, must make any model the multi-purpose aggregate machine-tool to succeed, the workshop needs to provide the skilled machinist, has ability and completes many kinds of operations nimbly. Therefore, crosswise training was at any time in the past more important. Regarded as the milling and the lathe work the different belongs to their time. Regarding personnel who will program, will understand the engine bed and controls it, this will be their ability manifestation.The cutting tool will choose most people not to install the passenger vehicle tire to the race car on, but processed the cutting tool to have such situation. The cutting tool should match with the new engine bed, is conceivably redundant on the new engine bed uses the old cutting tool to the production efficiency influence. In order to match the multi-purpose aggregate machine-tools, the new cutting tool and the cutting tool adapter technology was already developed. At present the industrial field is developing the development the processing cutting tool, may complete the turning on the identical tool rest, boring and drills truncates the processing, is only processes the phase to differ from regarding the work piece angle. The processing operates the difference even confuses is unclear. The new processing cutting tool may complete the milling and the turning. The machinery automation technology first starts from the 1920s in the machine manufacture cold finishing production in enormous quantities process to develop the application, after in the 60s, to adapt the market demand and the change, for the enhancement machine-building industry to the market nimble rapid reaction's ability, starts to establish the variable automation production system,namely revolves the computer technology the flexible automation. It is in the manufacture system invariable or in the change small situation, the machinery equipment either production management process through the automatic detection, the information processing, the analysis judgment realizes the anticipated operation or some kind of process automatically, and can from make one kind of components to transform automatically to makes another kind of different components. The social practice proved that under this kind of definition's manufacture system automation and the contemporary majority enterprises are not actually accommodating. The contemporary society also not in the science and technology, the material and the personnel aspect prepares to realize this automated condition, insists such to do only meets the wasted effort. This kind of situation is not exceptional regarding the separate production method's machine-building industry, the difficulty can bigger.The aggregate machine-tool future development more use transmissions and so on variable speed motor and ball bearing guide screw,will simplify structure, the reduction production metre; Uses the numerical control system and the headstock, the jig automatic replacement system, enhancesthe craft controllability; As well as integrates the flexible manufacture system and so on.中文译文多用途组合机床对于多功能组合机床，在工业领域有许多名字来描述它，如“多任务处理装置”，“多功能机床”，“多工序生产系统”等，它确实可称为加工领域的新星，可降低成本，简化配置，和一直保持在美国本土生产。

机械毕业设计英文外文翻译609组合机床现状与前景

ⅡAggregate machine-tool and from generatortechnological developmentIn uses the CNC three coordinates processing’s module from the generator in and transfers the tow the aggregate machine-tool and the aggregate machine-tool from the generator are one kind of special-purpose highly effective automation technical equip, at present, because it still was the mass mechanical product realization is highly effective, high grade and the efficient production key equipment, thus is widely applied to the automobile, the tractor, the internal combustion engine and the compressor and soon many industrial productions domain. Among them, specially the automobile industry, is the aggregate machine-tool and from the generator biggest user. If the German populace automotive factory in the Slaughter engine factory, the metal-cutting machine tool which at the beginning of the 90's uses mainly is from the generator (60%),the aggregate machine-tool (20%) and the processing center (20%).Obviously, in the mass production mechanical industry sector, the equipmentwhich massively uses is the aggregate machine-tool and from the generator. Therefore, aggregate machine-tool and its from the generator technical performance and the synthesis automation level, has decided these industry sector products production efficiencies, the product quality and the ent erprise production organization’s structure in the very great degree, also has decided the enterprise product competitive ability in the very great degree.The modern aggregate machine tool and from the generator took the integration of machinery product, it is technical the and so on control, actuation, survey, monitoring, cutting tool and mechanical module synthesis reflection. In the recent 20 years, these technologies have make great strides, simultaneously as aggregate machine-tool main profession and so on user's automobile and internal combustion engine also has the very big change, its produce market life unceasingly reduces, the variety increases day by day also the quality unceasingly enhances. These factors powerfully impelled and have driven the aggregate machine tool and from the generator technology unceasing development.1Aggregate machine-tool variety development keyIn aggregate machine-tool this kind of special purpose machine, the rotation type multiplex position aggregate machine-tool and holds thievery important status from the generator. Because these two kind of engine beds may assign the work piece many processing’s working procedure to many Canadian location in, and at the same time can carryon the processing from many directions to the work piece several surface, in addition, but also may through the indexing jig (on rotary table engine bed) or through indexing, the turn over installment (inform generator in) realizes the work piece five processing’s or completely processes, thus has the very high automat city and the production efficiency, by industry sector and so on the automobile, motorcycle and compressor uses.According to related statistical data, Germany in 1,990 ~ in 1992period, the rotation type multiplex position aggregate machine-too land approximately respectively accounts for the aggregate machine-tool total from the generator output about 50%.Should point out that, the rotation type multiplex position tool-tool is in fact one kind of special pattern small from the generator, suits to processing overall size <= 250mm center small. With compares from the generator, in the processing identical kind of work piece situation, the rotation type multiplex position tool-tool occupies the work area to have to be approximately smaller than from the generator 2/3.2 Further reduces from the generator meter timeAt present, take the mass production as the characteristic passenger vehicle and the light truck, its engine annual output usually is about600, 000, the realization such great volume production, the rotation type multiplex position aggregate machine-tool and from the generator in three class of movements situations, its meter time generally is 20~ 30 seconds, when the components production batch is bigger, the engine bed meter time also must shorter (table 1). In the 70's, must realize the such short meter from the generator, often must use the compound double location or the establishment double thread means, namely to decides from the generator meter,the working procedure time longest processing working procedure to have through the parallel two same proc essing’s location, if the restrictive working procedure are more time, then through uses two same from the generator balances from generator system processing meter. Obviously, like this must increase the equipment investment and the work area.Reduces the non-cutting time mainly is reduces including the work piece transportation, the processing module fast introduction as wells the processing module by quickly enters transforms enters after the labor cuts into the time to the cutting tool which the work piece spend. In order to reduce this part of spatial travel time, generally uses enhance the work piece (work piece direct transportation) or accompanies the jig the transfer rate and the processing module rapid traverse speed. At present, accompanies the jig the transfer rate tube possible to reach 60m/min or higher, the processing module rapid traverse speed reaches 40m/min. At present, accompanies the jig high speed feed way commonly used to have the proportion valve to control or the cycloid actuation feedway. At the end of the 70's, Hon berg Corporation has used the feed way in its processing gear box body from the generator in which the proportion valve controls. Should from generator long 18.2m, some 12 Canadian location, transportation step of distance be 1400mm, the transportation weights 7000kg, the transfer rate reaches 45.6m/min, step of distance transportation time is only 2.5s. Chart 4 is this feed way state of motion curve. Because the proportion valve control system haste good start and the braking quality, also the system structure is simple, until now, this kind of feed way still many is used from the generator.3 Aggregate machine-tool flexibility progress is rapidMore than ten for years, took the aggregate machine-tool important user the automobile industry, for caters to the people individuality demand, the automobile aberration variety increases day by day, launches the competition by the multi- varieties to become one of auto market competition characteristics, this causes the tool-tool manufacturing industry to face is changing form thematic- varieties production challenge. In order to adapt themulti-varieties production, the tradition processes the sole variety the rigidity aggregate machine tool and must enhance its flexibility from the generator. In the 70's, the numerical control system reliability had the very big enhancement, therefore to at the end of the 70's and at the beginning of the 80's, like Align, Hüller-Hille and company and so on Ex-cell-o develops the numerical control processing module and the flexibility one after another from the generator, from this time on the numerical control aggregate machine-tool and the flexibility increase year by year from the generator. From 1988 to1992, the Japan aggregate machine-tool and (including partial other forms special purpose machine) the output numerical control rate has reached 32% from the generator ~ 39%, the output value numerical control ratio reaches 35% ~ 51%; The Germany aggregate machine-too land from the generator output numerical control rate is 18% ~ 62%, the output value numerical control rate reaches 45% ~ 66%. These numerals indicated that, in the recent ten years, the tool-tool numerical control development is extremely rapid. Should point out that, since has entered for the 90's, the auto market competition hastens intensely, the produce market lifefurther reduces, the new vehicle type development cycle reduces (at present generally is day by day 35 months), the automobile variety unceasingly increases, thus the automobile industry increases day by day to the flexible automation technical equip demand quantity. If the Japanese Toyota car company, is the company subordinate factory flexibility processing system popular rate achieves 100% in this century's end goal. Very obviously, the aggregate machine tool and its at maintains its high production efficiency from the generator under the condition, further enhances its flexibility on increasingly to have the vital significance.The aggregate machine-tool flexibility mainly is through uses the numerical control technology to realize. The development flexibility aggregate machine-tool and the flexibility develops the numerical control processing module from the generator important premise, but has the longer development history the processing center technology to provide the mature experience for the development numerical control processing module. Flexibility aggregate machine-tool and flexibility’scomposed which by the numerical control processing module from generator, the passable application and the change numerical control procedure realizes from moves the knife, automatically replaces the change processing traveling schedule, the operating cycle, the cutting parameter as well as processes the position and soon, adapts the aberration variety processing. The flexibility aggregate machine-tool and the flexibility the numerical control processing module which use from the generator, according to its numerical control coordinates (axis) the number, mainly has the single coordinates (Z), the double coordinates (X-Z, Y-Z, Z-U and Z-B and soon) and three coordinates (X-Y-Z) processes the module; According toots main axle number, has the single axle and the multiple spindle processing module, also has the single axle and the multiple spindle compound process.The column moves the type CNC three coordinates processing’s module tube possible to use X axis and the Y axis linkage realizes the peripheral craft, specially when gear box body this kind of rigidity worse work piece, mayuse compares the minor diameter the milling cutter, the realization is high speed (cutting speed to reach 2500m/min) peripheral, from this reduces time the processing the work piece distortion. This uses the double coordinates processing module with the large diameter milling cutter to carry on much more superior than. The multiple spindle-processing module is another kind of important module, mainly uses in to process the box body and the plate class work piece flexibility aggregate machine-tool and the flexibility from the generator. This kind of module has the many kinds of different structural style, but basically may divide into from moves the box type multiple spindle processing module (chart 7), transfers the tower system multiple spindle processing module (chart 8) and the rotation work table model multiple spindle processing module (chart 9). From moves the box type module because may specially establish in many storehouses stores up therefore may use for to process more different varieties the work piece. But transfers the tower system and the rotation work table model multiplespindle processing module, because allows the rotary table which installs to be limited (generally is 4 ~ 6), therefore this kind of processing module only can realize the limited variety processing system multiple spindle processing module, not only may realize the different variety work piece processing, moreover in from generator meter time in (if metre adequate time), this kind of processing module also may in the identical Canadian location through it from moves the knife or trades the box, realizes the multi channel processing working procedure (to bethink in turn The drill hole, drills outland attacks the silk), thus reduces from the generator processing labor figure, reduces from the generator length. The single axle and the multiple spindle compound processing module is one kind of three coordinates numerical controls processing module, passable from has moved the knife either automatically replaces realizes the single axle processing or the multiple spindle processing. Is worth mentioning, Corporation promotes the CNCMACH modulation system in 80'sintermediate stages Germany Hon berg (chart 10) is hasthe characteristic very much one kind of modular system, this system full application modulation structure principle, in took the system base module in the CNC three coordinates module, through fluctuates each kind of different function module, assembles Cheng Gashing the different coordinates or does not use the craft use the processing module. To be specific, looking from the coordinates, besides three coordinates, but also may the group form a pair the coordinates and the single coordinates processing module; Looking from the knife storehouse that, may install the cutting tool store house may alone realize the cutting tool automatic replacements, also may realize the cutting tool replacements in turn.CNC MACH system, not only in mechanism aspect, moreover in aspect ands on control and software also is the modulation. Therefore, uses this system module, may very conveniently assemble the flexibility from the generator (FTL), the flexible processing unit (FMC) or the flexible manufacture system (FMS). Besides above each kind of CNCprocessing module, the robot and the servo actuatethe jig also are the flexibility aggregate machine-tool and the flexibility from the generator important part. Specially in the flexibility from the generator in, at present comparatively generally has used the Dragon Gate type spatial frame robot to carry on the work piece on the automatic yummy treats, uses in work piece indexing or the turn over. In order to transport the different work piece, may in from the generator nearby the establishment fingernail storehouse, the realization fingernail automatic replacement. The jig provides the servo drive, adapts in the work piece race the different work piece automatically to clamp. Chart 11 shows are a processing carrying capacity truck eight kind of gearboxes bodies’ flexibility from the generator. This line uses the numerical control processing module has four double coordinates numerical controls module, six numerical controls transfers the tower system multiple spindle processing module and six numerical controls three coordinates processing module. The auxiliary location has cleans the location and uses the robot to carry on the operation the attire to clamp the workstation.Because composes from the generator processing module all is the numerical control, when by one kind of work piece processing transformation for another kind of work piece processing, only must be good through the change numerical control procedure, but did not need to carry on aspect the and so on machinery adjustment and the equipment.The aggregate machine-tool reduces day by day from the generator flexibility rapid development and the meter time, fully had demonstrated the CNC technology and the cutting tool technology the huge technology advancement which bring for the aggregate machine-tool automatic line, causes the flexibility from the generator in thematic- varieties, the mass production to become the important technical equip. But must point out in here that, during the tool-tool and from generator realization flexibility development, the processing center high-speed development exceptionally is rapid. At the beginning of the 90's, the flexible production line which discomposed by this kind of high speed processing center enter the mass realm of production, appeared the processing center and from thegenerator competition aspect.------ Rajput R K Elements of Mechanical Engineering.

中英文文献翻译-组合机床与控制设计

英语原文：Integrated Machine and Control DesignAbstract—In this paper, we describe a systematic design procedure for reconfigurable machine tools and their associated control systems. The starting point for the design is a set of operations that must be performed on a given part or part family. These operations are decomposed into a set of functions that the machine must perform and the functions are mapped to machine modules, each of which has an associated machine control module. Once the machine is constructed from a set of modules, the machine control modules are connected. An operation sequence control mod ule, user interface control module, and mode-switching logic complete the control design. The integration of the machine and control design and the reconfigurability of the resulting machine tool are described in detail.I. IntroductionIn today’s competitive markets, manufacturing systems must quickly respond to changing customer demands and diminishing product life cycles. Traditional transfer lines are designed for high volume production, operate in a fixed automation paradigm, and therefore cannot readily accommodate changes in the product design. On the other hand, conventional CNC-based “flexible” manufacturing system offer generalized flexibility but are generally slow and expensive since they are not optimized for any particular product or a family of products.An effort at the University of Michigan aims to develop the theory and enabling technology for reconfigurable machining systems. Instead of building a machining system from scratch each time a new part is needed, an existing system can be reconfigured to produce the new part. In this paper, we describe how an integrated machine and control design strategy can result in machine tools which can be quickly and easily configured and reconfigured.In order to provide exactly the functionality and capacity needed to process a family of parts, RMTs are designed around a given family of parts. Given a set of operations to be performed, RMTs can be configured by assembling appropriate machine modules. Each active module in the library has a control module associated with it. As the mechanical modules are assembled, the control modules will be connected and the machine will be ready to operate. Extensive and time-consuming specialized control system design will not be required. Section II describes how the machine is designed from a set of basic machine modules,This research was supported in part by the NSF-ERC connected in a well-defined fashion, and Section III describes how the control is similarly assembled from a library of control modules. This modular construction of the machine and control allows formany levels of reconfigurability as described in Section IV. The paper concludes with a description of future work in Section V.II. Machine DesignOngoing work on manufacturing system configuration at the University of Michigan addresses the problem of starting from a part (or part family) description and extracting the machining operations necessary to produce the part(s). The operations are grouped according to tolerance, order of execution, and desired cycle time of the system, with the intention that each operation “cluster” can be produced on a single machine tool. The operation cluster considered here is to drill a set of holes for the cam tower caps on V6 and V8 cylinder heads shown in Figure 1. The input to the reconfigurable machine tool design procedure is the cutter location data generated by a process planner for this operation cluster. data includes positioning and drilling information.The RMT design procedure consists of three main stages: task clarification, module selection, and evaluation. After a brief literature review, these three stages will be outlined in this section.A. Related researchSince reconfigurability is a relatively new concept in ma chining systems, there is little, if any, published literature on the design of reconfigurable machine tools. However, modular machine tools have been on the market for several years, and some of the published articles on modular robots, modular machines and assembly do have some rel-evance to the design of reconfigurable machine tools. For example, Shinno and Ito proposed a methodology for generating the structural configuration of machine tools. They decomposed the machine tool structures into simple geometric forms: e.g. boxes, cylinders, etc. Yan and Chen [21], [1] extended this work to the ma chining center structural design. [12] adapted Ito’s method for modular machine t ool synthesis and de-veloped a method for enumerating machine tool modules. Paradis and Khosla [15] determined the modular assembly configuration which is optimally suited to perform a specific task. On the systems front, Rogers and Bottaci [16] discussed the significance of reconfigurable manufacturing systems, and Owen et al. [13] developed a modular reconfigurable manufacturing system synthesis program for educational pur poses.In our work, traditional methods of motion representation and topology (i.e. screw theory, graph theory, etc.) are employed to capture the characteristics of RMTs. These mathematical schemes are used for topological synthesis, function-decomposition, and mapping procedures; details can be found in [9].Figure 1B.Task clarificationThe design of an RMT begins with task clarification, which entails analyzing the cutter location data to determine the set of functions which are necessary to accomplish the desired kinematic motions. There are three steps. First, graphs are generated which abstractly representationFig. 3. High-level operation sequence, showing causal dependencies and concurrencies.This abstract representation of the sequence of operations is derived from the CL data, and will be used to design the sequencing control the motions. These graphs are then decomposed into functions, and finally the functions are mapped onto machine modules which exist in the library.A graph representation of the machine tool structure allows for systematic enumeration of alternate configurations and also provides a method of identification of nonisomorphic graphs. The graph representation is also used for bookkeeping to assign machine modules to the graph elements. A graph consists of a set of vertices connected together by edges. In using a graph as an abstract represen tation of a machine tool structure, we define two different types of vertices: type 0 and type 1. A vertex represents a physical object with two ports; each port represents the location on the object where it can be attached to a neighboring object. A type 0 vertex has input and output ports that are in-line with respect to each other, whereas a type 1 vertex has input and output ports that are perpendicular to each other. Machining tasks are also classified as type 0 or type 1, depending on whether the tool is parallel or per pendicular to the workpiece.C. Module selectionCommercially available modules are selected from the module library for each ofthe functions (structural as well as kinematic) that were mapped to the graph in the task clarification stage. The data stored for each module in the library includes the homogenous transformation matrix representing its kinematic or structural function, the twist vector supplemented by range of motion information, a compliance matrix representing the module stiffness, module connectivity information, and power requirements (for active modules such as spindles and slides).The first step in module selection is to compare the homogeneous transformation matrices of the modules with the task requirement matrix such that when appropriate modules are selected to meet the task requirements, the product of all module matrices should be equal to the desired task matrix: T = T1· T2 · · · Tn. Again, there may be many possible choices of modules for a given structural configuration. Figure 6 shows how different slides, spindles, and structural elements can be assembled according to the graph of Figure 4.A slide module, with its CAD model and transformation matrix, is shown in Figure7. It is capable of one direction of linear motion, indicated by the ~1 variable in its transformation matrix. Its database entry, shown in Table I, stores not only its transformation matrix but also the manufacturer name, model number, initial position, power level, and motion data. The twist vector is augmented by information on the minimum, initial, and maximum displacement of the module.TABLE IDatabase information and documentation for the machinemodule shown in Figure 7.(a) V6 machine (b) V8 machineFig. 2. Reconfigurable machine tool designs for the two different parts.D. EvaluationOnce a set of kinematically-feasible modules have been selected, the resulting machine design must be evaluated. The criteria for evaluation of the reconfigurable machine tools synthesized by the above systematic procedure include the work envelope, the number of degrees of freedom, the number of modules used, and the dynamic stiffness.The number of kinematic degrees of freedom of the machine tool must be kept to a minimum required to meet the requirements, both to reduce the actuation power and minimize the chain of errors. Machine tool designs which are generated using this methodology for the example parts of Figure 1 are shown in Figure 8.The resulting designs must be evaluated with respect to the expec ted accuracy. The stiffness of the entire machine tool, one of the most important factors in performance, is estimated based on the module compliance matrices and the connection method.III. Control DesignAs the machine is built from modular elements, so is the control. In this work, we focus on the logic control for sequencing and coordination of the machine modules; a discrete-event system formalism is used [6]. There is one control module associated with each active machine module; we refer to these as machine control modules. In the machine design, there are passive elements which connect the active elements together. In the control design, there must also be“glue” modules which connect the machine control modules. The overall architecture of the control system for an RMT is shown in Figure 9.The structure is similar for either of the two machines shown in Figure 8; for the V8 machine, there is no Y -axis control module. As shown, the machine control modules are at the lowest level; these interact directly with the mechanical system. Three modules handle the mode switching logic. In this section, we briefly describe each of these types of control modules as well as their interaction and coordina tion.A. Machine control modulesEach machine control module has awell-defined interface specification: itaccepts discrete-event commands from agiven set, and returns discrete-eventresponses from a given set. Within thecontrol module will be all of the continuous-variable control, such as servo control foraxes. This continuous control is designedusing standard PID algorithms and the axisparameters such as inertia, power, lead screw pitch, which come from the machine module definition. In addition, each machine control module will contain con trols for any machine services associated with the machine module, such as lubrication or coolant. Thus, each machine control module is a self-contained controller for the machinemodule itaccompanies, and can bedesigned andtestedindependentlyof the rest ofthe machine.Fig.10.Slide ControllerThe design of a machine control module must be done only once for each machine module in the library. Whenever the machine module is used in a machine design, the control module can be used in the associated control design. The control module may be used independently, with its own processing power, I/O and a network connection to the rest of the control system, or it may be used as a piece of the overall machine controller which is implemented in a centralized fashion.B. Operation sequenceThe operation sequence module is defined from the high level sequence extracted from the cutter location data shown in Figure 3.C. Modular control structureThe user interface control module interacts with the user through a set of pushbuttons to turn the control system on and off, switch between control modes, and single-step through the operation sequence. Its main functions are to pass the user commands through to the rest of the controller, and to display the current state of the machine to the user.IV. Conclusions and Future WorkHistorically, machine tool design has been experience based. In this research, we described a mathematical basis for synthesis and evaluation of Reconfigurable Machine Tools and their associated controllers. This research work has addressed both the generation of machine tool configurations and modular control design. The systematic design process begins with the machining requirements.The presented methodology for synthesis of machine tools allows a library of machine modules to be precompiled and stored in a database, self-contained with con-trollers and ready to be used in any machine design. The methodology also ensures that all kinematically viable and distinctly different configurations are systematically enu-merated to reduce the chance of missing a good design.We have already developed a Java-based program which automates the machinedesign process; we are currently incorporating the control design procedure withi n the existing framework.The authors would like to acknowledge the support and invaluable feedback from the industrial members of the ERC who have participated in this project.中文译文组合机床与控制设计摘要——在本文中，我们描述一个系统的设计程序的可重构机床及其控制系统。

中英文资料外文翻译文献TRANSFER AND UNIT MACHINEWhile the specific intention and application for transfer and unit machine vary from one machine type to another, all forms of transfer and unit machine have common benefits. Here are but a few of the more important benefits offered by TRANSFER AND UNIT MACHINE equipment.The first benefit offered by all forms of transfer and unit machine is improved automation. The operator intervention related to producing workpieces can be reduced or eliminated. Many transfer and unit machine can run unattended during their entire machining cycle, freeing the operator to do other tasks. This gives the transfer and unit machine user several side benefits including reduced operator fatigue, fewer mistakes caused by human error, and consistent and predictable machining time for each workpiece. Since the machine will be running under program control, the skill level required of the transfer and unit machine operator (related to basic machining practice) is also reduced as compared to a machinist producing workpieces with conventional machine tools.The second major benefit of transfer and unit machine technology is consistent and accurate workpieces. Today's transfer and unit machines boast almost unbelievable accuracy and repeatability specifications. This means that once a program is verified, two, ten, or one thousand identical workpieces can be easily produced with precision and consistency.rd benefit offered by most forms of transfer and unit machine tools is flexibility. Since these machines are run from programs, running a different workpieceis almost as easy as loading a different program. Once a program has been verified and executed for one production run, it can be easily recalled the next time the workpiece is to be run. This leads to yet another benefit, fast change over. Since these machines are very easy to set up and run, and since programs can be easily loaded, they allow very short setup time. This is imperative with today's just-in-time (JIT) product requirements.Motion control - the heart of transfer and unit machineThe most basic function of any transfer and unit machine is automatic, precise, and consistent motion control. Rather than applying completely mechanical devices to cause motion as is required on most conventional machine tools, transfer and unit machines allow motion control in a revolutionary manner2. All forms of transfer and unit machine equipment have two or more directions of motion, called axes. These axes can be precisely and automatically positioned along their lengths of travel. The two most common axis types are linear (driven along a straight path) and rotary (driven along a circular path).Instead of causing motion by turning cranks and handwheels as is required on conventional machine tools, transfer and unit machines allow motions to be commanded through programmed commands. Generally speaking, the motion type (rapid, linear, and circular), the axes to move, the amount of motion and the motion rate (feedrate) are programmable with almost all transfer and unit machine tools.A transfer and unit machine command executed within the control tells the drive motor to rotate a precise number of times. The rotation of the drive motor in turn rotates the ball screw. And the ball screw drives the linear axis (slide). A feedback device (linear scale) on the slide allows the control to confirm that the commanded number of rotations has taken place3. Refer to fig.1.Fig.1Though a rather crude analogy, the same basic linear motion can be found on a common table vise. As you rotate the vise crank, you rotate a lead screw that, in turn, drives the movable jaw on the vise. By comparison, a linear axis on a transfer and unit machine machine tool is extremely precise. The number of revolutions of the axis drive motor precisely controls the amount of linear motion along the axis.How axis motion is commanded - understanding coordinate systemsIt would be infeasible for the transfer and unit machine user to cause axis motion by trying to tell each axis drive motor how many times to rotate in order to command a given linear motion amount4. (This would be like having to figure out how many turns of the handle on a table vise will cause the movable jaw to move exactly one inch!) Instead, all transfer and unit machine controls allow axis motion to be commanded in a much simpler and more logical way by utilizing some form of coordinate system. The two most popular coordinate systems used with transfer and unit machines are the rectangular coordinate system and the polar coordinate system. By far, the more popular of these two is the rectangular coordinate system.The program zero point establishes the point of reference for motion commands in a transfer and unit machine program. This allows the programmer to specify movements from a common location. If program zero is chosen wisely, usually coordinates needed for the program can be taken directly from the print.With this technique, if the programmer wishes the tool to be sent to a position one inch to the right of the program zero point, X1.0 is commanded. If the programmer wishes the tool to move to a position one inch above the program zero point, Y1.0 is commanded. The control will automatically determine how many times to rotate each axis drive motor and ball screw to make the axis reach the commanded destination point . This lets the programmer command axis motion in a very logical manner. Refer to fig.2, 3.Fig.2Fig.3All discussions to this point assume that the absolute mode of programming is used6. The most common transfer and unit machine word used to designate the absolute mode is G90. In the absolute mode, the end points for all motions will be specified from the program zero point. For beginners, this is usually the best and easiest method of specifying end points for motion commands. However, there is another way of specifying end points for axis motion.In the incremental mode (commonly specified by G91), end points for motions are specified from the tool's current position, not from program zero. With this method of commanding motion, the programmer must always be asking "How far should I move the tool?" While there are times when the incremental mode can be very helpful, generally speaking, this is the more cumbersome and difficult method of specifying motion and beginners should concentrate on using the absolute mode.Be careful when making motion commands. Beginners have the tendency tothink incrementally. If working in the absolute mode (as beginners should), the programmer should always be asking "To what position should the tool be moved?" This position is relative to program zero, NOT from the tools current position.Aside from making it very easy to determine the current position for any command, another benefit of working in the absolute mode has to do with mistakes made during motion commands. In the absolute mode, if a motion mistake is made in one command of the program, only one movement will be incorrect. On the other hand, if a mistake is made during incremental movements, all motions from the point of the mistake will also be incorrect.Assigning program zeroKeep in mind that the transfer and unit machine control must be told the location of the program zero point by one means or another. How this is done varies dramatically from one transfer and unit machine and control to another8. One (older) method is to assign program zero in the program. With this method, the programmer tells the control how far it is from the program zero point to the starting position of the machine. This is commonly done with a G92 (or G50) command at least at the beginning of the program and possibly at the beginning of each tool.Another, newer and better way to assign program zero is through some form of offset. Refer to fig.4. Commonly machining center control manufacturers call offsets used to assign program zero fixture offsets. Turning center manufacturers commonly call offsets used to assign program zero for each tool geometry offsets.Fig. 4Flexible manufacturing cellsA flexible manufacturing cell (FMC) can be considered as a flexible manufacturing subsystem. The following differences exist between the FMC and the FMS:1.An FMC is not under the direct control of thecentral computer. Instead, instructions from the centralcomputer are passed to the cell controller.2.The cell is limited in the number of part families itcan manufacture.The following elements are normally found in an FMC:•Cell controller•Programmable logic controller (PLC)•More than one machine tool•A materials handling device (robot or pallet)The FMC executes fixed machining operations with parts flowing sequentially between operations.High speed machiningThe term High Speed Machining (HSM) commonly refers to end milling at high rotational speeds and high surface feeds. For instance, the routing of pockets in aluminum airframe sections with a very high material removal rate1. Over the past 60 years, HSM has been applied to a wide range of metallic and non-metallic workpiece materials, including the production of components with specific surface topography requirements and machining of materials with hardness of 50 HRC and above. With most steel components hardened to approximately 32-42 HRC, machining options currently include: Rough machining and semi-finishing of the material in its soft (annealed) condition heat treatment to achieve the final required hardness = 63 HRC machining of electrodes and Electrical Discharge Machining (EDM) of specific parts of dies and moulds (specifically small radii and deep cavities with limitedaccessibility for metal cutting tools) finishing and super-finishing of cylindrical/flat/cavity surfaces with appropriate cemented carbide, cermet, solid carbide, mixed ceramic or polycrystalline cubic boron nitride (PCBN)For many components, the production process involves a combination of these options and in the case of dies and moulds it also includes time consuming hand finishing. Consequently, production costs can be high and lead times excessive.It is typical in the die and mould industry to produce one or just a few tools of the same design. The process involves constant changes to the design, and because of these changes there is also a corresponding need for measuring and reverse engineering .The main criteria is the quality level of the die or mould regarding dimensional, geometric and surface accuracy. If the quality level after machining is poor and if it cannot meet the requirements, there will be a varying need of manual finishing work. This work produces satisfactory surface accuracy, but it always has a negative impact on the dimensional and geometric accuracy.One of the main aims for the die and mould industry has been, and still is, to reduce or eliminate the need for manual polishing and thus improve the quality and shorten the production costs and lead times.Main economical and technical factors for the development of HSMSurvivalThe ever increasing competition in the marketplace is continually setting new standards. The demands on time and cost efficiency is getting higher and higher. This has forced the development of new processes and production techniques to take place. HSM provides hope and solutions...MaterialsThe development of new, more difficult to machine materials has underlined the necessity to find new machining solutions. The aerospace industry has its heat resistant and stainless steel alloys. The automotive industry has different bimetal compositions, Compact Graphite Iron and an ever increasing volume of aluminum3. The die and mould industry mainly has to face the problem of machining highhardened tool steels, from roughing to finishing.QualityThe demand for higher component or product quality is the result of ever increasing competition. HSM, if applied correctly, offers a number of solutions in this area. Substitution of manual finishing is one example, which is especially important on dies and moulds or components with a complex 3D geometry.ProcessesThe demands on shorter throughput times via fewer setups and simplified flows (logistics) can in most cases, be solved by HSM. A typical target within the die and mould industry is to completely machine fully hardened small sized tools in one setup. Costly and time consuming EDM processes can also be reduced or eliminated with HSM.Design & developmentOne of the main tools in today's competition is to sell products on the value of novelty. The average product life cycle on cars today is 4 years, computers and accessories 1.5 years, hand phones 3 months... One of the prerequisites of this development of fast design changes and rapid product development time is the HSM technique.Complex productsThere is an increase of multi-functional surfaces on components, such as new design of turbine blades giving new and optimized functions and features. Earlier designs allowed polishing by hand or with robots (manipulators). Turbine blades with new, more sophisticated designs have to be finished via machining and preferably by HSM . There are also more and more examples of thin walled workpieces that have to be machined (medical equipment, electronics, products for defence, computer parts) Production equipmentThe strong development of cutting materials, holding tools, machine tools, controls and especially CAD/CAM features and equipment, has opened possibilities that must be met with new production methods and techniques5.Definition of HSMSalomon's theory, "Machining with high cutting speeds..." on which, in 1931,took out a German patent, assumes that "at a certain cutting speed (5-10 times higher than in conventional machining), the chip removal temperature at the cutting edge will start to decrease..."Given the conclusion:" ... seems to give a chance to improve productivity in machining with conventional tools at high cutting speeds..."Modern research, unfortunately, has not been able to verify this theory totally. There is a relative decrease of the temperature at the cutting edge that starts at certain cutting speeds for different materials.The decrease is small for steel and cast iron. But larger for aluminum and other non-ferrous metals. The definition of HSM must be based on other factors.Given today's technology, "high speed" is generally accepted to mean surface speeds between 1 and 10 kilometers per minute or roughly 3 300 to 33 000 feet per minute. Speeds above 10 km/min are in the ultra-high speed category, and are largely the realm of experimental metal cutting. Obviously, the spindle rotations required to achieve these surface cutting speeds are directly related to the diameter of the tools being used. One trend which is very evident today is the use of very large cutter diameters for these applications - and this has important implications for tool design.There are many opinions, many myths and many different ways to define HSM. Maintenance and troubleshootingMaintenance for a horizontal MCThe following is a list of required regular maintenance for a Horizontal Machining Center as shown in fig.5. Listed are the frequency of service, capacities, and type of fluids required. These required specifications must be followed in order to keep your machine in good working order and protect your warranty.fig. 5DailyTop off coolant level every eight hour shift (especially during heavy TSC usage).Check way lube lubrication tank level.Clean chips from way covers and bottom pan.Clean chips from tool changer.Wipe spindle taper with a clean cloth rag and apply light oil.Weekly•Check for proper operation of auto drain on filter regulator.On machines with the TSC option, clean the chip basket on the coolant tank.Remove the tank cover and remove any sediment inside the tank.

Solutions given are intended to give the individual servicing the TRANSFER AND UNIT MACHINE a pattern to follow in, first, determining the problem's source and, second, solving the problem.Use common senseMany problems are easily overcome by correctly evaluating the situation. All machine operations are composed of a program, tools, and tooling. You must look at all three before blaming one as the fault area. If a bored hole is chattering because of an overextended boring bar, don't expect the machine to correct the fault.Don't suspect machine accuracy if the vise bends the part. Don't claim hole mis-positioning if you don't first center-drill the hole.Find the problem firstMany mechanics tear into things before they understand the problem, hoping that it will appear as they go. We know this from the fact that more than half of all warranty returned parts are in good working order. If the spindle doesn't turn, remember that the spindle is connected to the gear box, which is connected to the spindle motor, which is driven by the spindle drive, which is connected to the I/O BOARD, which is driven by the MOCON, which is driven by the processor. The moral here is don't replace the spindle drive if the belt is broken. Find the problem first; don't just replace the easiest part to get to.Don tinker with the machineThere are hundreds of parameters, wires, switches, etc., that you can change in this machine. Don't start randomly changing parts and parameters. Remember, there is a good chance that if you change something, you will incorrectly install it or break something else in the process6. Consider for a moment changing the processor's board. First, you have to download all parameters, remove a dozen connectors, replace the board, reconnect and reload, and if you make one mistake or bend one tiny pin it WON'T WORK. You always need to consider the risk of accidentally damaging the machine anytime you work on it. It is cheap insurance to double-check a suspect part before physically changing it. The less work you do on the machine the better.组合机床虽然各种组合机床的功能和应用各不相同，但它们有着共同的优点。

Development and application of combined machine tool The combination of machine tools based on general parts, workpiece supported by the specific shape and design of special processing of parts and fixtures, the composition semiautomatic or automatic special machine. Combination machine generally adopts multi shaft, knife, more processes, more or multiple locations simultaneously processes, and production efficiency ratio general machine tool high several times to several times. As generic components have been standardized and serialized, may need to be flexible configuration, can shorten design and manufacturing cycle. Therefore, the aggregate machine-tool has the advantages of high efficiency and low cost, the large, mass production to be widely applied, and can be used to compose the automatic production line. Processing, workpiece generally does not rotate, by movement of the rotatable cutter and tool and workpiece relative feed movement, to achieve drilling, reaming, counterboring, reaming, boring, milling, cutting and processing of external thread face and etc.. Some combination machine adopts clamping workpiece machining head to rotate, by the tool for the feed movement, also can achieve some rotating parts ( such as car rear axle flywheel, etc.) of the face and processing.In twentieth Century since the 70's, along with the cutting tool with indexable inserts, dense gear milling cutter, boring size automatic detection and automatic compensation for tool technology development, combination of the machining accuracy of the machine tool is improved. Milling plane plane of up to 0.05mm and1000 mm, the surface roughness can be as low as 2.5to 0.63 microns; boring accuracy up to IT7~6, hole distance precision can reach 0.03~ 0.02 micron. A dedicated machine is along with the automobile industry development. In some parts of special machine tool for repeated use, and gradually developed into a general components, resulting in a combined machine tool. The earliest combination machine is made in the United States in 1911, for the processing of auto parts. Initially, the machine tool manufacturingplant has its own general component standard. In order to improve different factory universal interchangeability of the parts, and is convenient for users to use and repair.The Design ProcessDesigning starts with a need real.Existing apparatus may need improvements in durability, efficiency, weight, speed, or cost. New apparatus may be needed to perform a function previouslydone by men, such as computation, assembly, or servicing. With the objective wholly or partlyIn the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint., namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.When the general shape and a few dimensions of the several components become apparent, analysis can begin in earnest. The analysis will have as its objective satisfactory or superior performance, plus safety and durability with minimum weight, and a competitive cost. Optimum proportions and dimensions will be sought for each critically loaded section, together with a balance between the strengths of the several components. Materials and their treatment will be chosen. These important objectives can be attained only by analysis based upon the principles of mechanics, such as those of static for reaction forces and for the optimum utilization of friction; of dynamics for inertia, acceleration, and energy; of elasticity and strength of materials for stress and deflection; of physical behavior of materials; and of fluid mechanics for lubrication and hydrodynamic drives. The analyses may be made by the same engineer who conceived the arrangement of mechanisms, or, in alarge company, they may be made by a separate analysis division or research group. Design is a reiterative and cooperative process, whether done formally or informally, and the analyst can contribute to phases other than his own. Product design requires much research and development. Many Concepts of an idea must be studied, tried, and then either used or discarded. Although the content of each engineering problem is unique, the designers follow the similar process to solve the problems.Machinery design covers the following contents.1. Provides an introduction to the design process , problemformulation ,safety factors.2. Reviews the material properties and static and dynamic loading analysis ,Including beam , vibration and impact loading.3. Reviews the fundamentals of stress and defection analysis.4. Introduces fatigue-failure theory with the emphasis on stress-life approaches to high-cycle fatigue design, which is commonly used in the design of rotation machinery.5. Discusses thoroughly the phenomena of wear mechanisms, surface contact stresses ,and surface fatigue.6. Investigates shaft design using the fatigue-analysis techniques.7. Discusses fluid-film and rolling-element bearing theory and application8. Gives a thorough introduction to the kinematics, design and stress analysis of spur gears , and a simple introduction to helical ,bevel ,and worm gearing.9. Discusses spring design including compression ,extension and torsion springs.10. Deals with screws and fasteners including power screw and preload fasteners.11. Introduces the design and specification of disk clutches and brakes.。

翻译文献：INVESTIGATION ON DYNAMIC PERFORMANCE OF SLIDE UNIT IN MODULAR MACHINE TOOL （对组合机床滑台动态性能的调查报告）文献作者：Peter Dransfield,出处：Peter Dransfield, Hydraulic Control System-Design and Analysis of TheirDynamics, Springer-Verlag, 1981翻译页数：p139—144英文译文：对组合机床滑台动态性能的调查报告【摘要】这一张纸处理调查利用有束缚力的曲线图和状态空间分析法对组合机床滑台的滑动影响和运动平稳性问题进行分析与研究，从而建立了滑台的液压驱动系统一自调背压调速系统的动态数学模型。

通过计算机数字仿真系统，分析了滑台产生滑动影响和运动不平稳的原因及主要影响因素。

从那些中可以得出那样的结论，如果能合理地设计液压缸和自调背压调压阀的结构尺寸.本文中所使用的符号如下：s1-流源，即调速阀出口流量；S el—滑台滑动摩擦力R一滑台等效粘性摩擦系数：I1—滑台与油缸的质量12—自调背压阀阀心质量C1、c2—油缸无杆腔及有杆腔的液容；C2—自调背压阀弹簧柔度；R1, R2自调背压阀阻尼孔液阻，R9—自调背压阀阀口液阻S e2—自调背压阀弹簧的初始预紧力；I4, I5—管路的等效液感C5、C6—管路的等效液容：R5, R7-管路的等效液阻；V3, V4—油缸无杆腔及有杆腔内容积；P3, P4—油缸无杆腔及有杆腔的压力F—滑台承受负载，V—滑台运动速度。

本文采用功率键合图和状态空间分折法建立系统的运动数学模型，滑台的动态特性可以能得到显著改善。

一、引言在组合机床正常工作中，滑台运动速度的大小和它的方向以及所承受负载的变化都将以程度不同地影响其工作性能。

特别是在工进过程中。

滑台上负载的突然消失引起的前进以及负载的周期性变化而引起的运动不平稳性，都将影响被加工件的表面质量，在严重的情况下会使刀具折断掉。

根据大连机床厂要求，作者采用有束缚力的曲线图和状态空间分析法建立组合机床滑台的新型液压驱动系统一自调背压调速系统的动态数学模型。

为了改善滑台的动态特性，有必要去分析找出滑台产生前冲和运动不平稳的原因以及主要的影响因素，但那必须通过计算机数字仿真和研究得出最后的结果。

二、动态数学模型组合机床滑台的液压驱动系统一自调背压调速系统的工作原理图如图I所示。

这个系统是用来完成"工进一停止一快退”的工作循环。

当滑台在工进时，三位四通换向阀处于图示右位，油泵的供油压力在滥流阀的有效作用下近似地几乎保持恒定，该油液流经过换向阀和调速阀后进入油缸的无杆腔，以推动滑台向前移动；与此同时，从油缸有杆腔排出的压力油经自调背压阀和换向阀流回油箱了。

在这个过程中，两个单向阀和溢流阀的工作状态始终都没有任何变化。

对与象组合机床滑台的液压驱动系统一自调背压调速系统这样的复杂非线性的系统，为了便于研究它的动态特性，建立一个仅着重考虑主要影响因素的合理简单的动态数学模型是尤其重要的[1][2]。

从理论分析和试验研究的列举中可以得知：该系统的过程时间是远大于调速阀的过程时间的，当油缸无杆腔有效承压面积很大时，调速阀出口流量的瞬时的超调反映为滑台运动速度的变化是很小的[2]。

为了更加拓宽和深入研究系统的动态特性，使研究工作能在微型计算机上有效地进行，本文章对原模型[2]做进一步简化处理，假定调速阀在系统的整个通过过程中输出时候恒定的流量，这被看作其为流源。

这样，系统的动态模型的结构简图如图2所示，它是由油缸、滑台，自凋背压阀和联接管路等组成。

功率键合图是一功效流图，它是按着系统的能量传递方式，以实际结构为基础，用集中参数把子系统之间的作用关系抽象地表示为阻性元R、容性元C和感性元I 的三种作用元。

采用这种方法建模物理概念清晰，结合状态空间分析法可以较准确地描述和分析线性系统，该方法在时域中研究复杂非线性系统动态特性的一种有效的方法。

根据自调背压调速系统各元件的主要特性和建模规则[1]，得出了图3所示的系统的功率键合图。

图中每根键上的半箭头表示功率流向，构成功率的两个变量是力变量（油压P或作用力F）和流变量（流量q或速度v）。

O结点表示在系统中属于并联连接，各键上的力变量相等而流变量之和为零；1结点表示在系统中属于串联连接，各键上流变量相等而力变量之和为零。

TF表示不同能量形式间的变换器，TF 下标注的字母表示力变量或流变量的转换比值。

键上的短横杠表示该键上两变量间的因果关系。

全箭头表示控制关系。

在三种作用元中容性元和感性元的力变量与流变量之间具有积分或微分关系，因此，根据图3可推导出具有九个状态变量的复杂非线性状态方程。

本文对滑台动态特性的研究是从滑台的前冲和运动平稳性两方面入手，用四阶定步长Runge-Kutta法在IBM-PC微型计算机上进行数字仿真,仿真结果分别如图4和图5所示。

三、滑台前冲滑台前冲现象是作用在滑台上的负载突然消失（如钻削工作的情况)引起的。

在此过程中，滑台的负载F、运动速度V、油缸两腔压力P3和P4的变化可从图4仿真结果看出。

当滑台在负载的作用下匀速运动时，油缸无杆腔油液压力较高．油液中聚集了大量的能量。

当负载突然消失时，该腔油压随之迅速降低，油液从高压态转入低压态的过程中向系统释放很多能量，致使滑台高速向前冲击。

然而，滑台的前冲使油缸有杆腔油液受压引起背压升高，从而消耗掉系统中的一部分能量，对滑台的前冲起到一定的抑制作用。

应当看到，在所研究的系统中，自调背压阀的入口压力要受到油缸两腔油压的综合性作用。

在负载消失的瞬间，自调背压阀的压力将会迅速地上升，并稳定地处在高于初始背压的数值以上。

从图中可见，自调背压调速系统在负载消失瞬间油缸背压力升高的幅度大于传统的调速系统，所以，其油缸有杆腔中油液吸收的能量就多；结果，滑台的前冲量比传统调速系统要小大约20%。

可见采用自调背庄调速系统作为驱动系统的滑台在抑制前冲方面具有良好的特性，其中自调背压阀起了很大作用。

四、滑台的运动平稳性当作用于滑台上的负载作周期变化时（比如说铣削加工的情况），滑台的运动速度将要产生一定的波动。

为于保证加工质量的要求，必须尽可能地减小其速度波动的范围。

而从讨论问题的方便性出发来说，假设负载按正弦波的规律变化，从而得到的数字仿真结果如图5所示。

由此可见这个系统与传统的调速系统有着相同的变化规律以及非常接近的数值数字。

其中的原因是负载的变化幅度不大，油缸两腔的压力也就没有较大变化，从而最终导致自调背压阀的作用不够明显显示。

五、改善措施通过研究的结果表明，以自调背压调速系统作为驱动系统的滑台，其动态特性要比传统的调速系统好的。

要减少滑台的前冲量，就必需在负载消失的瞬间时候迅速提高油缸有杆腔的背压力；要提高滑台的运动平稳性就需增加系统的刚性，主要措施在于减小油液的体积。

从系统的结构得知，油缸有杆腔与排油管之间有一很大的容积，如图6a所示。

它的存在方面延迟和衰减了自调背压阀的作用，另一方面也降低了系统的刚性，它会限制了前冲特性和运动平稳性的进一步改善。

因此，改善滑台动态特性可从两个方法进行处理：即改变油缸容积和改变自调背压阀结构尺寸。

通过一系统结构性参数的仿真计算以及结果的比较可以得出这样的结果：当把油缸有杆腔与排油管间容积V4同无杆腔与进油管间容积V3之比由原来的5.5改为1时，如图6b所示，同时，把自调背压阀阀芯底端直径由原来的10mm增加为13mm,阻尼三角槽边长从原来的lmm减小到0.7mm时，可使滑台的前冲量减小30%,过渡过程时间明显缩短了，滑台的运动平稳性也将会得到很大的改善。

六、结论通过理论上的分析和计算机仿真研究实验,很明显的是自调背压调速系统作为组合机床滑台的驱动系统是很有推广使用价值的。

影响滑台动态特性的主要因素是油缸内部结构性和自调节背压阀的尺寸。

假如能对其进行合理设计，可使滑台的动态特性得到显著地改善。

同时，也说明了采用有束缚力的曲线图和状态空间分析法研究复杂非线性液压系统的动态特性是既方便又有效的方法。

The dynamic mathematical model of self-adjusting back pressure speed control system used to drive slide unit is established. Main reasons and affect-ing factors for slide unit impact and motion unstability are analysed through compu-ter digital simulation, It is concluded from those that, if the structural dimensions of hydraulic cylinder and back pressure valve are designed rationally, the slide unit's dynamics will markedly be improved.NOMENCLATURESf flow sourceSei sliding friction force in slide unitR equivalent viscous friction coefficient in slide unitIi mass of slide unit and cylinderh mass of SABP valve spoolCi,C2hydraulic capacitances of rod chamber and non-rod chamber in cylinder re-spec-tivelyC3spring compliance of SABP valveR]r R2hydraulic resistances of damping holesR9hydraulic resistance of orifice of SABP valveSe2presetting force of spring in SABP valveI4J5equivalent liquid inertia in pipe linesC^Cg equivalent hydraulic capacitances in pipe linesequivalent hydraulic resistances in pipe linesV-j V^oil-containing volumes in non-rod chamber and rod chamber respectivelyP,r:, P-i oil pressures in non-rod chamber and rod chamber respectivelyF load acted on slide unitV slide unit velocity* Department of Mechanical Engineering, Dalian Ur.iversity of Technology, Dalian. China.INTRODUCTIONDuring operation of modular machine tool, the changes of slid unit's speed and load acted on it in both magnitude and direction will affect working performar.ee to a different extent Particularly the impact caused by sudden vanishing of load and the motion unstability due to periodical change of load in operation will affect the surface quality of the workpiece machined, and the tool would be broken off under serious conditions, By using the method of power bond graph and state space analysis, the dynamic mathematical model of the system used to drive slide unit is established, that is called as self-adjusting back pressure speed control system and abbreviated to SABP system. In order to improve slide unit's dynamics, it is necessary to find out the main reasons and affecting factors, that must be based on computer digital simulation and study on the results.DYNAMIC MATHEMATICAL MODELThe schematic diagram of SABP system is shown in Fig.l, the system is used to perform the cycle of feeding, stopping and returning. Four way control valve works in the right position during slide unit's feeding. The supply pressure of the pump is approximately constant under the action of pressure relief valve, the oil through the control valve and pressure compensated flow control valve enters the non-rod chamber to put slide unit forward. At the same time, the oil from the rod chamber is discharged through SABP valve and directional control valve to tank. In this process, the state of two check valves and pressure relief valve is not changed, To establish the mathematical model as reasonably and simply as possible, consid-eration must be focused on main affecting factors for a complex non-linear system such as the SABP system. It is illustrated by theoretical analysis and test result ' , that the transient time of the system is much longer than that of the flow control valve, and the flowrate overshoot of the valve in transients affects very small to slide unit speed because of the ;large effective sectional area of non-rod chamber in cylinder. For investigating the system's dynamics widely and deeply, the initial mod-el tn is further simplified in this paper, and so the study can be efficiently made with microcomputer. It is assumed that the flowrate through the flow control valve isconstant in the whole transient process, and is denoted to a flow source.Fig.2 shows the structure diagram of the dynamic model of the system, it is composed of cylin-der, slide unit, SABP valve and pipe line; etc.By using the method of power bond graph and state space analysis in this paper, the dynamic mathematical model of the system is to be established- The power bond graph is a power flow diagram, which expresses abstractly the actions among sub-systems as three effects, i.e. resistance effect, capacitive effect and inertia effect, according to the way of energy transform, on the basis of practical structure and by means of method of lumped parameters. The model is characterized by a clear con-ception in physics, and non-linear system can be accurately analysed in combination with method of state space analysis, thus it is a effective method used in the dyna-mic investigation of complex non-linear system in the'timedomain.From main performances of components in SAEP system, the power bond graph of the system has been formed by means of the rule of model establishing ' and is shown in Fig.3. Half arrow in each bond indicates a direction of power How, two variahles of power are effort variable and flow variable. O-junction illustrates algebraic summation of flow variables at common effort, i.e. parallel connection, 1-junction does algebraic summation of effort variables at common flow, i.e. series connection. The symbol TF represents power transformer between two types of energy, and transforming modulus between efforts or flows is noted below the symbol TF. Short transverse bar across one end of each bond shows causality between two variables. A full arrow expresses a control action. Among three actions, there is an integration or differential form in capacitive effect and inertia effect between two variables. So state equation may be derived from Fig.3, there are nine state variables in this complex nonlinear equation. Studying on the slide unit's dynamics is started with impact and motion stability. The equation is simulated by using the method of 4th order Runge-Kutta integration procedure on IBM-PC computer. Fig.4 and Fig.5 illustrate the results respectively.SLIDE UNIT IMPACTSlide unit's impact phenominon results from load's vanishing in the transients, ■ for example, the situation of drilling through workpiece, Fig.4 expounds the variations of the load and speed of slide unit, the pressures of chambers in cylinder. When slide unit motions evenly under the action of load, the oil pressure in non-rod chamber is very high, and there is a lot of hydraulic energy accumulated in side. The pressure decreases at once with load's discharging rapidly. During the process of oil pressure converting from high to low, the system absorbs some of the energy, so slide unit impacts forward with high speed. And then the oil in rod chamber is141compressed to increase back pressure, some of the energy is consumed, which plays a part of restraining the impact of the slide unit. It must be noted that inlet pressure of SABP valve telys on the interaction of pressures of two chambers, and increases rapidly at the instant of load's vanishing, and then stabilizes at some value greater than initial one. This pressure is also greater than one of traditional speed control system, therefore the energy can be absorbed much more in the rod chamber. In result, the impact of slide unit in SABP system is 20% lawer than in traditional's. It is thus clear that slide unit with SABP system for driving has a good performance in restraining the impact and SABP valve plays an important part in that,MOTION STABILITYWhen load acting on slide unit varies periodically, such as the situation of mill-ing, slide unit's speed will bring about some pulse. In order to meet the requirements of manufacturing quality, the magnitude of the speed pulse must be reduced as small as possible. The variation of the load is assumed to be of sine wave, in order to sim-plify discussion of the problem, The result of digital simulation is shown in Fig.5 It can be seen that, the response of the system is the sameas traditionl's and the differ-ences between them are very small. The reason for this is that the variation of the load is not targe, there the pressures in chambers vary very little that is, the effect of the SABP valve is not obvious.IMPROVEMENTIt is shown by studying, that dynamics of slide unit which used SABP speed control system as driving system is better than that of traditional system. To reduce the slide unit's impact, the back pressure of rod chamber has to be increased rapidly in the transients of load's vanishing; on the other hand, to enhance the slide unit's motion stability, it is necessary to raise the system rigidity. However, main recom-mendation lies in decreasing the volume of oil. It is known from system structure that, there is a lot of oil-containing volume between the rod chamber and drain pipe as shown in Fig.6a. Because the volume exists, not only the effect of SABP valve is delayed and reduced, hut also the rigidity of the system is decreased. Therefore, it is hindered to further improve the impact and motion stability. To make the slide unit dynamics better, the structural dimensions of cylinder's chamber and the SABP valve must be designed suitably. Based on simulations under the various structural dimensions and comparison among the results, the following two measures can be taken for improvements:the ratio between volumeV4 and V3 is changed from 5.5 to 1 approximately, as shown in Fig,6b;142the bottom diameter of spool of the SABP valve is increased from 10 mm to 13 mm and.the length of side of triangular damping slot is decreased from 1 mm to 0.7mm the slide unites impact quantity can be reduced by 30%, and the time of dynamic response is shortened. In addition, slide unit's motion stability may be improved obviously. It is thus evident that improvements are very effective.CONCLUSIONSBy the way of theoretical analysis and computer simulating investigation, it is obvious that the SABP speed control system used as slide units driving system in modular machine tool is valuable for popularization and utilization, Main factors affecting the slide unit dynamics are the structural dimensions of the cylinder and the SABP valve. In the case of rationally designing, the slide unit dynamics may be obviously improved. Meanwhile, it is shown that the method of power bond graph and state space analysis is a very convenient and effective method in studying dynamics of complex non-linear hydraulic system.REFERENCES[1] Peter dransfield Hydraulic Control System-Design and Analysis of TheirDynamics Springer-Verlag, 1981[2] Dong Bengang, Zhang Zhixiang, Investigation on impact property ofselfadjusting back pressure speed control system.
