机械专业英语短文带翻译
机械工程师的关键责任之一是设计与分析机械系统。这涉及使用计算机辅助设计（CAD）软件创建系统的详细三维模型，并在不同条件下模拟其性能。通过分析作用于系统组件的力、应力和振动，机械工程师可以优化设计，确保安全、可靠和高效。
Case Study: Designing an Automotive Suspension System
案例研究：汽车悬挂系统设计
例如，让我们考虑一下汽车悬挂系统的设计。悬挂系统负责在保持车辆稳定控制的同时提供平稳的行驶。机械工程师使用CAD软件设计悬挂系统的各个组件，例如弹簧、减振器和控制臂。
在完成初始设计后，工程师将使用有限元分析（FEA）软件对系统进行分析。这样可以模拟系统在不同的道路条件下（如坑洼或减速带）的行为。通过分析组件中的应力和位移，工程师可以确定潜在的设计问题，并进行必要的修改，以改善悬挂系统的性能和安全性。
For example, let's consider the design of an automotive suspension system. A suspension system is responsible for providing a smooth ride while maintaining the stability and control of the vehicle. A mechanical engineer would use CAD software to design the various components of the suspension system, such as the springs, dampers, and control arms.
After the initial design is complete, the engineer would then analyze the system using finite element analysis (FEA) software. This allows them to simulate the behavior of the system under different road conditions, such as potholes or speed bumps. By analyzing the stresses and displacements in the components, the engineer can identify potential design issues and make necessary modifications to improve the performance and safety of the suspension system.

Metals have the greatest importance for industry. All machines and other engineering[7endVi5niEriN] constructions have metal[5metl] parts; some of them consistonly of metal parts.众所周知,金属在我们的生活中是非常重要的,金属对于工业而言是有巨大的重要性,所有机器和其他工程构造都有金属零部件,其中一些还只能由金属组成.There are two large groups of metals:1) Simple metal- more or less pure chemical elements[5elimEnt]2) Alloys[5AlCi]- materials consisting of a simple metal combined with some other elements.有两大类金属:（1）纯金属——或多或少的金属元素（2）合金——组成纯金属的原料结合其他元素.About two thirds of all elements found in the earth are metals, but not all metals may be used in industry. Those metals which are used in industry are called engineering metals. The most important engineering metal is iron[5aiEn], which in the form of alloys with carbon[5kB:bEn] and other elements, finds greater use than any other metal. Metals consisting of iron combined with some other elements are known as ferrous[5ferEs] metals; all the other metals are called nonferrous[5nCn5ferEs] metals. The most importantnonferrous metal are copper[5kCpE], aluminum[E5lju:minEm], lead[li:d], zinc[ziNk], tin[tin], but all these metals are used much less than ferrous metals, because the ferrous metals are much cheaper.第 _._._._. 在地球上发现的所有元素中,大约三分之二是金属元素,但是并不是所有的金属都能够用于工业上.那些金属—我们用于工业上的金属—被称为工程金属,最重要的工程金属那就是铁,铁跟碳和其他元素结合形成合金的那些金属比其他金属发现有更大用途.铁与别的其他某些元素相结合而组成的金属称为黑色金属,此外所有其他金属都称为有色金属,最重要的有色金属是---铜,铝.铅.锌.锡.但是使 _课的翻译暂时没有. 用这些有色金属比使用黑色金属要少的多,因为黑色金属便宜得多.Engineering metals are used in industry in the form of alloys because the properties[5prCpEti] of alloys are much better than the properties of pure[pjuE] metals. Only aluminum may be largely used in the form of simple metal. Metals have such a great importance because of their useful properties or their strength, hardness, 翻译标准.请放心使 and their plasticity[plAs5tisiti].因为合金的特性比纯金属的好,所以工程金属以合金的形式用于工业,只有铝以纯金属的形式被广泛应用.金属因为具有强度.硬度和可塑性而发挥着特别重要的作用. 用.Different metals are produced in different ways, but almost all the metal are found in the forms of metal ore[C:(r)] (iron ore, copper ore, etc[et cetra].)以不同的方法生产不同的合金但是几乎所有的金属都是以金属矿的形式（铁矿.铜矿）被发现的.The ore is a mineral[5minErEl] consistence of a metal combined with some impurities[im5pjuEriti].

Te_t:12. Plastics and Other MaterialsTe_t:Plastics[5plAstik, plB:stik] have specific properties which may makeik] acids[5AsId], such as sulphuric[sQl5fjuErik] acid and hydrochloric[7haidrEu5klC:rik] acid. Plastics tend to be resistant to these acids, but can have dissolved or deformed by solvent[5sClvEnt], suchas carbon tetrachloride[7tetrE5klC:raid], which have the same carbon base as the plastics. Color must be applied to the surface of metals, whereas it can be mi_ed in with plastics. Metals are more rigid[5ridVid] than most plastics while plastics are very light, with a specific[spi5sifik] gravity normally between 0.9 and 1.8. Most plastics do not readily[5redili] conduct[5kCndQkt] heat or electricity[Ilek5trIsItI]. Plastics soften slowly and can easily be shaped[Feip] when they are soft.塑料具有特殊的性能.对于某种用途而言,这些性能使得塑料比传统材料更为可取.例如,跟金属相比较,塑料既有优点也有缺点.金属易受到无机酸的腐蚀,如硫酸和盐酸,塑料能抵抗这些酸的腐蚀,但可被溶剂所洛解或引起变形,例如溶剂四氯化碳与塑料具有同样的碳基.颜色必定只能涂到金属的表面.而它可以跟塑料混合为一体.金属比大多数塑料刚性要好,而塑料则非常之轻,通常塑料密度在0. 9-1. 8之间.大多数塑料不易传热导电.塑料能缓慢软化,而当其还是在软的状态时,能容易成形.It is their plasticity[plAs5tisiti] at certain temperatures[5temprItFE(r)] which gives plastics their main advantages over many other materials. It permits the large-scale production of molded[mEuld] articles, such as containers, at an economic unit cost, where other materials require laborious[lE5bC:riEs] and often costly processes involving cutting, shaping, machining, assembly[E5sembli] and decoration.在某一温度下塑料是处于塑性状态的,这就使塑料具备超过许多其他材料的主要优点.它容许大量生产单位成本低廉的模制式器件,例如,各种容器.于此,若用其他材料则需要大量劳力和往往需要很费钱的加工工艺,比如,切割.成形.加工.装配和装饰.Plastics not only replace other materials. Their properties can be e_ploited[iks5plCit] for entirely[In5taIElI] new applications. For e_ample, plastics heart valves[vAlv] and other human spare parts have make possible many recent developments in surgery[5sE:dVEri].塑料不仅可以代替其他材料,而且它的特性能被开拓应用于全新领域,比如:随着最近外科手术的发展可能做成塑料的心脏瓣膜和其他人类的器官.There is no single plastics material which is suitable for all applications. It is important that the most suitable plastics should be chosen, and if necessary adapted[E5dApt], for each particular requirement. It is also important that the properties of the plastics chosen should be e_ploited to the best advantage.没有一种纯塑料材料适用于各个领域,如果有必要改进,对于每个有特殊要求的来说选择最合适的塑料是最重要的,被选择的塑料材料的特性被开拓得到更好的应用也是很重要的.A plastics article may need to differ in design and appearance from a similar article made from another material such as metal or wood. This is due[ ] not only to the properties of plastics but also to thetechniques[tek5ni:k] employed in fabricating[5fAbrikeit] plastics. These techniques include injection[in5dVekFEn] molding[5mEuldiN], blow molding, compression molding, e_trusion[eks5tru:VEn] and vacuum[5vAkjuEm] forming.塑料器件可能需要用其他材料比如:与金属或木材制作的类似的器件从设计和外观上加以区别,这不仅是由于塑料性能不同的原因,也是由于制造塑料产品所用的技术不同所致,这些技术包括:注塑.模制.吹塑模制.压模.挤压和真空成型等.23. Casting and Die-Casting AlloysTe_t:Casting[5kB:stiN] is one of the oldest metal working techniques known to man. Our country made metal castings as early as _ B.C., and the process used then is not much different in principle[5prinsEpl] from the one used today.铸造是入类所掌握的最古老的金属加工技术之一.我国早在公元前 _年就已把金属制成铸件,而所使用的工艺从原理上和今天的工艺没有多大的区别.Foundry[5faundri]processesconsistof makingmolds,preparingandmelting[melt]themetal, pouring[pC:, pCE] the metal into the molds, and cleaning the castings. The product of the foundry is a casting, which may vary from a fraction[5frAkFEn] of a kilogram to several hundred tons. It may also vary in composition[kCmpE5ziFEn] as practically all metals and alloys can be cast.铸造工艺由制模.备料和金属熔炼,金属液浇注入模和铸件清砂等.铸造的产品是铸件,铸件可能从零点几公斤到几百吨范围变化.实际上所有金属在成分上也是变化的,而合金也可以铸造.The metals most frequently cast are iron, steel, aluminum and so on. Of these, iron, because of its low melting point, low price and ease of control, is outstanding for its suitability[9sjU:tE`bIlEtI] for casting and is used far more than all the others.最常铸造的金属是铸铁.钢.铝等等.这些金属中,铸铁,由于其低熔点,低价格和易控制,因而其铸造适应性是最突出的,而且使用也远比所有其他金属多.Castingisawidelyusedmethodofproducingmetalproducts,particularlythosew hichareintricate[5intrikit]. Since molten materials will readily take the shape of the container into which they are poured, it is nearly as easy to cast fairly comple_ shapes as to produce simple forms.由于熔融的物料能容易取得被浇注进去的容器（模型）的形状,因此,几乎像生产简单形状铸件那样颇为容易地铸造出复杂形状的铸件.The place where the metals are cast is called a foundry. The most important of cast metals is cast iron which is made from pig iron by remelting it in a special melting furnace[5fE:nis] called a cupola[5kju:pElE].铸造金属的地方叫做铸造车间.最重要的铸造金属是铸铁,铸铁是用生铁在一个特殊的熔炉—叫冲天炉的炉子中重新熔炼而制造出来的.From the cupola, the cast iron flows into ladles[5leidl] of different size, and from these ladles it is poured into the molds.从冲天炉中出来的铁水流入到不同规格的铁水包中,并从这些铁水包中被浇注到模型中.The molds may be of two kinds: sand molds and metal molds. A metal mold consists of two hollow parts which should be joined for pouring the metal into it. The inside of this mold is covered with carbon or graphite[5 Afait] so that the metal could not stick[stik] to the wall of the form. When the metal has solidlocks of steel produced by pouring the metal into these molds are called ingots and the process is called ingot casting.模型有两种类型:砂模和金属模.金属模是由两个中空的部件组成,它们应被联结在一起以便将金属液浇入模箱中.这模腔的内侧是要涂以碳粉或石墨,因此金属不玫于粘贴到型腔壁上口当金属液凝固后,这中空的型箱部件被打开并取出铸件.也有一种特殊模型,在该模型中可以铸造大型钢块.这些模型通常用铸铁米制造,并被称为锭模.而浇注金属液到这些模子中生产出的钢块被称为钢锭.该工艺过程叫锭铸.A relatively[5relEtIvlI] wide range of nonferrous alloys can be die-cast. The principal base metals used, in order to commercial importance, are zinc, aluminum, copper, magnesium[mA ni:zjEm], lead, and tin. The alloys may be further classified as low-temperature alloys and high-temperature alloys; those having a casting 3temperature below 538C, such as zinc, tin, and lead, are in the low-temperature class. The low-temperature alloys have the advantages of lower cost of production and lower die-maintenance[5meintinEns] costs. As the casting temperature increases, alloy and other special steels in the best treated condition are required to resist the erosion[i5rEuVEn] and heat checking[5tFekiN] of die surface.

ForgingTe_t:Press forging[5fC:dViN] employs a slow squeezing[skwi:z] action in deforming[di:5fC:m] the plastic metal, as contrasted with the rapid-impact[5impAkt] blows of a hammer. The squeezing action is carried completely to the center of the part being pressed, thoroughly working the entire section[5sekFEn]. These presses are the vertical[5vE:tikEl] type and may be either mechanically[mi5kAnikEli] or hydraulically[hai5drC:lik] operated. The mechanical presses, which are faster operating and most commonly used, range in capacity[kE5pAsiti] from 5_ to 1_0 tons.与锤锻的快速冲击不同,压力机锻造是用缓慢的挤压作用使塑性金属变形.这挤压作用完全被施加到正在被压锻的零件中心位置上,直至彻底使整个工件得到加工.这些压力机都是立式的,可能是机械操作也可能是液压操作的.机械操作压力机,操作速度比较快,使用最普遍,锻造能力从 5_吨到1__吨范围.For small press forgings, closed impression dies are used and only one stoke of the ram[rAm] is normally required to perform[pE5fC:m] the forging operation. The ma_imum[5mAksimEm] pressure is built up at the endof the stroke which forces the metal into shape. Dies may be mounted[maunt] as separate units, or all the cavities may be put into single block. Forsmall forgings, individual[7indi5vidjuEl] die unites are more convenient. There is some difference in the design of dies for different metals; copper-alloy forgings can be made withless draft[drB:ft] than steel,consequently more complicated[5kCmplikeitid]shapes can be produced. These alloys flow well in the die and are rapidly e_truded 对于小型压力锻使用闭式锻模.通常要求锻锤仅一个冲程就完成锻造工艺.在冲程终端产生最大压力,该冲击压力迫使金属成形.模具可由各白独立的单元装配而成,即把所有个别模腔都放到一起,组成整体.对于小型锻件使用分模装置更为方便.对于不同的金属在模具设计上有些区别 .铜合金锻件比钢件用较小的拔模斜度,因此可生产更加复杂形状的锻件.这些合金在该种模具中流动性好,而且能快速挤压成形.In the forging press, a greater proportion of the total work put into the machine is transmitted[trAnz5mit] to the metal than in a drop hammer press. Much of the impact of the drop hammer is absorbed by the machine and foundation. Press reduction of the metal is faster, and the cost of operation is consequently lower. Most press forgings are symmetrical[si5metrikEl] in shape, having surfaces which are quite smooth, and provide a closer tolerance[5tClErEns] than is obtained by a drop hammer. However, many parts of irregular[i5re…ulE] and complicated shapes can be forged more economically by drop forging. Forging press is often used for sizing operations on parts made by other forging processes.锻压机比落锤锻,输入到机器里的总能量中有更大部分的能量被传输到金属坯料上.落锤锻的冲击能量被机器和基础吸收得较多(比起压力机来〕.金属上的压力衰减较快,因此生产成本比较低.大多数压力锻锻件形状.产生的表面都是对称的,而且表面非常光滑,并比落锤锻件的公差尺寸更加精确.然而落锤锻造可以锻制形状复杂而不规则的锻件,因而较为经济.锻压机常常用来为其他锻造工艺所生产的锻件进行整形和校正加工用.In drop forging, a piece of metal, roughly[5rQflI] or appro_imately of the desired[di5zaiE] shape, is placed between die faces having the e_act form of the finished piece, and forced to take thin form by drawing the dies together. Large ingots are now almost always forged with hydraulic presses instead of with steam hammers, sinc。

Based cross-sectional area of the small piston is S1, plus a small piston in the downward pressure on the F1. Thus, a small piston on the liquid pressure to P = F1/SI,Can be the same size in all directions to the transmission of liquid. By the large piston is also equivalent to the inevitable pressure P. If the large piston is the cross-sectional area S2, the pressure P on the piston in the upward pressure generated F2 = PxS2 Cross-sectional area is a small multiple of the piston cross-sectional area. From the type known to add in a small piston of a smaller force, the piston will be in great force, for which the hydraulic machine used to suppress plywood, oil, extract heavy objects, such as forging steel.History of the development of hydraulicAnd air pressure drive hydraulic fluid as the transmission is made according to the 17th century, Pascals principle of hydrostatic pressure to drive thedevelopment of an emerging technology, the United Kingdom in 1795 Joseph (Joseph Braman ,1749-1814), in London water as a medium to form hydraulic press used in industry, the birth of the worlds first hydraulic press.

机械制造专业英语4B原文及翻译(章跃主编)
CHAIN DRIVESChain drives occupy a unique position in the mechanical field.In a sense,they are similar to belt drives;a chain connects sprockets on the driving and driven shafts.The velocity ratio transmitted from one shaft to the other depends on the size of the two sprockets(at the pitch line);unlike that found with belts,the ratio is positive.In belt drive ,creep and slip play important roles and must be considered;in a chain drive,which is made up of numerous links,there is a small amount of play in the total length of the chain.This may be desirable in case of small overloads.A chain drive is similar to the open-belt type of dirve in that the driving and driven shafts rotate in the same direction.There are also similarities between chain drives and gear drives.Both types transmit a positive velocity ratio.In a regular spur-gear drive,the driving and driven shafts turn in opposite directions unless an idler is employed.In gear drives employing an annular or ring gear,however,the input and output shafts rotate in the same direction.In a spur-gear drive there is very little contact between meshing gears;therefore,tooth loads are excessive.Since the connection between a chain and its sprocket extends over several teeth,no one tooth is subjected to heavy loads.Chain drives are often noisy.The silent chain type of drive was developed to counteract this undesirable characteristic.Belt,chain,and gear drives are all dangerous.Belt and chain speeds are high,as is the pitch-line velocity of most gear drives.All should be adequately covered by suitable guards(or completely enclosed) so that no boby or clothing parts can possibly be caught in the moving components.Other comparisons can be made among chain,belt,and gear drives.Gear drives can operate at higher speeds than the others,and are usually more compact.However,chain drives do not require the mounting precision that is so essential for gearing.An advantage of chain drives in comparison to belt drives is that the former do not require tension on the slack side;this leads to better bearing life.In general,chain drives are more compact than the belt type;for a given ratio,the sprockets can be smaller than belt pulleys.For a given load,chain widths are narrower than comparable flat belts.The connecting link on chain drives makes them easy to install—the chain is merely placed over the sprockets and the proper pins are placed in position.In most belt installations,force is needed to place the belt in the proper position;such action is detrimental to mounting bearings.The angle of contact for the driving sprocket can be smaller than the driving pulley for a belt drive.For a chain drive,this angle can be as small as 120 degrees.The center distance can also be small;if a 120-degree angle of contact is provided,the center distance need be no more than just enough to provide clearance for the sprocket teeth.An essential part of any chain drive is the sprocket.A chain drive requires a sprocket on the driving shaft and another on the driven shaft.Chain drives sometimes contain additional sprockets,used for additional power take-offs or for taking up chain slack.When used to take up chain slack,they are known as idlers.Idlers should be mounted on the slack side,not on the tight side.It is desirable to have an adjustment for idler positioning where possible.Fig.4-5 showsa roller-chain sprocket.Sprocket teeth are standardized to accommodate the roller chain.Various sizes of sprockets may be used,and several types are available.The simplest type is one without a hub.Sprockets are also available with hubs on one side or on both sides.Special arrangements are also possible.Certain of these are used in conjunction with a shear-pin hub;the shear pin is designed to fail in case of an accidental or unexpected overload.Some types can be installed on large lineshafts;these sprockets are made in two parts so that they can be installed without disconnecting the long length of shafting.Smaller sprockets are usually made solid;large ones are sometimes constructed with arms or spokes to reduce weight.In general,the selection of a sprocket depends on the type of application.链传动链传动在机械领域中占据了独特的地位。

Numerical control technology in the world at present and equiping the development trend to see, there is the following several respect [1- ] in its main research focus .1.1 A high-speed , high finish machining technology and new trend equippedThe efficiency , quality are subjavanufacturing technology. High-speed , high finish machining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market competitive power. Japan carries the technological research association first to classify it as one of the 5 great modern manufacturing technologies for this, learn (CIRP ) to confirm it as the centre in the 21st century and study one of the directions in international production engineering.In the field of car industry, produce one second when beat such as production of 300,000 / vehicle per year, and many variety process it is car that equip key problem that must be solved one of; In the fields of aviation and aerospace industry,spare parts of its processing are mostly the thin wall and thin muscle, rigidity is very bad, the material is aluminium or aluminium alloy, only in a situation that cut the speed and cut strength very small high, could process these muscles , walls . Adopt large-scale whole aluminium alloy method that blank " pay empty " make the wing recently, such large-scale parts as the fuselage ,etc. come to substitute a lot of parts to assemble through numerous rivet , screw and other connection way, make the intensity , rigidity and dependability of the component improved. All these, to processing and equiping the demand which has proposed high-speed , high precise and high flexibility. According to EMO2001 exhibition situation, high-speed machining center is it give speed can reach 80m/min is even high , air transport competent speed can up to 100m/min to be about to enter.A lot of automobile factories in the world at present, including Shanghai General Motors Corporation of our country, have already adopted and substituted and made the lathe up with the production line part that the high-speed machining center makes up . HyperMach lathe of U.S.A. CINCINNATI Company enters to nearly biggest 60m/min of speed, it is 100m/min to be fast, the acceleration reaches 2g, the rotational speed of the main shaft has already reached 60 000r/min. Processing a thin wall of plane parts, spend 30min only, and same part general at a high speed milling machine process and take 3h, the ordinary milling machine is being processed to need 8h; The speed and acceleration of main shaft of dual main shaft lathes of Germany DMG Company are up to 12* separately! 000r/mm and 1g. In machining accuracy, the past 10 years, ordinary progression accuse of machining accuracy of lathe bring 5¦Ìm up to from 10¦Ìm already, accurate grades of machining center from 3- 5¦Ìm, rise to 1- 1.5¦Ìm, and ultraprecision machining accuracy is it enter nanometer grade to begin already (0.01¦Ìm). In dependability, MTBF value of the foreign numerical control device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . In order to realize high-speed , high finish machining, if the part of function related to it is electric main shaft , straight line electrical machinery get fast development, the application is expanded further.1.2 Link and process and compound to process the fast development of the lathe in 5 axesAdopt 5 axles to link the processing of the three-dimensional curved surface part, can cut with the best geometry form of the cutter , not only highly polished, but also efficiency improves by a large margin . It is generally acknowledged , the efficiency of an 5 axle gear beds can equal 2 3 axle gear beds , is it wait for to use the cubic nitrogen boron the milling cutter of ultra hard material is milled and pared at a high speed while quenching the hard steel part, 5 axles link and process 3 constant axles to link and process and give play to higher benefit. Because such reasons as complicated that 5 axles link the numerical control system , host computer structure that but go over, it is several times higher that its price links the numerical control lathe than 3 axles , in addition the technological degree of difficulty of programming is relatively great, have restricted the development of5 axle gear beds. At present because of electric appearance of main shaft, is it realize 5 axle complex main shaft hair structure processed to link greatly simplify to make, it makes degree of difficulty and reducing by a large margin of the cost, the price disparity of the numerical control system shrinks . So promoted 5 axle gear beds of head 无效 of complex main shaft and compound to process the development of the lathe (process the lathe including 5 ). At EMO2001 exhibition, new Japanese 5 of worker machine process lathe adopt complex main shaft hair, can realize the processing of 4 vertical planes and processing of the wanton angle , make 5 times process and 5 axles are processed and can be realized on the same lathe, can also realize the inclined plane and pour the processing of the hole of awls . Germany DMG Company exhibits the DMUVoution series machining center, but put and insert and put processing and 5 axles 5 times to link and process in once, can be controlled by CNC system or CAD/CAM is controlled directly or indirectly.1.3 Become the main trend of systematic development of contemporary numerical control intelligently , openly , networkedlilyThe numerical control equipment in the 21st century will be sure the intelligent system, the intelligent content includes all respects in the numerical control system: It is intelligent in order to pursue the efficiency of processing and process quality, control such as the self-adaptation of the processing course, the craft parameter is produced automatically; Join the convenient one in order to improve the performance of urging and use intelligently, if feedforward control , adaptive operation , electrical machinery of parameter , discern load select models , since exactly makes etc. automatically automatically; The ones that simplified programming , simplified operating aspect are intelligent, for instance intelligent automatic programming , intelligent man-machine interface ,etc.; There are content of intelligence diagnose , intelligent monitoring , diagnosis convenient to be systematic and maintaining ,etc..Produce the existing problem for the industrialization of solving the traditional numerical control system sealing and numerical control application software. A lot of countries carry on research to the open numerical control system at present, such as NGC of U.S.A. (The Next Generation Work-Station/Machine Control), OSACA of European Community (Open System Architecture for Control within Automation Systems), OSEC (Open System Environment for Controller ) of Japan, ONC (Open Numerical Control System ) of China ,etc.. The numerical control system melts to become the future way of the numerical control system open.The so-called open numerical control system is the development of the numerical control system can be on unified operation platform, face the lathe producer and end user, through changing, increasing or cutting out the structure target(numerical control function), form the seriation, and can use users specially conveniently and the technical know-how is integrated in the control system, realize the open numerical control system of different variety , different grade fast, form leading brand products with distinct distinction.System structure norm of the open numerical control system at present, communication norm , disposing norm , operation platform , numerical control systematic function storehouse and numerical control systematic function software developing implement ,etc. are the core of present research. The networked numerical control equipment is a new light spot of the fair of the internationally famous lathe in the past two years. Meeting production line , manufacture system , demand for the information integration of manufacturing company networkedly greatly of numerical control equipment, realize new manufacture mode such as quick make , fictitious enterprise , basic Entrance that the whole world make too.Some domestic and international famous numerical control lathes and systematic manufacturing companies of numerical control have all introduced relevant new concepts and prototypes of a machine in the past two years, if in EMO2001 exhibition, " CyberProduction Center " that the company exhibits of mountain rugged campstool gram in Japan (Mazak ) (intellectual central production control unit, abbreviated as CPC); The lathe company of Japanese big Wei (Okuma ) exhibits " IT plaza " (the information technology square , is abbreviated as IT square ); Open Manufacturing Environment that the company exhibits of German Siemens (Siemens ) (open the manufacturing environment, abbreviated as OME),etc., have reflected numerical control machine tooling to the development trend of networked direction.1.4 Pay attention to the new technical standard , normal setting-up1.4.1 Design the norm of developing about the numerical control systemAs noted previously, there are better commonability , flexibility , adaptability , expanding in the open numerical control system, such countries as U.S.A. , European Community and Japan ,etc. implement the strategic development plan one after another , carry on the research and formulation of the systematic norm (OMAC , OSACA , OSEC ) of numerical control of the open system structure, 3 biggest economies in the world have carried on the formulation that nearly the same science planned and standardized in a short time, have indicated a new arrival of period of change of numerical control technology. Our country started the research and formulation of standardizing the frame of ONC numerical control system of China too in 2000.1.4.2 About the numerical control standardThe numerical control standard is a kind of trend of information-based development of manufacturing industry. Information exchange among 50 years after numerical control technology was born was all because of ISO6983 standard, namely adopt G, M code describes how processes, its essential characteristic faces the processing course, obviously, he cant meet high-speed development of modern numerical control technologys needs more and more already. For this reason, studying and making a kind of new CNC system standard ISO14649 (STEP-NC) in the world, its purpose is to offer a kind of neutral mechanism not depending on the concrete system , can describe the unified data model in cycle of whole life of the products , thusrealize the whole manufacture process, standardization of and even each industrial field product information.The appearance of STEP-NC may be a revolution of the technological field of the numerical control, on the development and even the whole manufacturing industry of numerical control technology , will exert a far-reaching influence. First of all, STEP-NC puts forward a kind of brand-new manufacture idea , in the traditional manufacture idea, NC processes the procedures to all concentrate on individual computer. Under the new standard, NC procedure can be dispersed on Internet, this is exactly a direction of open , networked development of numerical control technology. Secondly, STEP-NC numerical control system can also reduce and process the drawing (about 75% ) , process the procedure to work out the time (about 35% ) and process the time (about 50% ) greatly . At present, American-European countries pay much attention to the research of STEP-NC, Europe initiates IMS plan (1999.1.1- 2001.12.3 ) of STEP-NC. 20 CAD/CAM/CAPP/CNC users , manufacturers and academic organizations from Europe and Japan participated in this plan. STEP Tools Company of U.S.A. is a developer of the data interchange software of manufacturing industry in the global range, he has already developed the super model (Super Model ) which accuses of information exchange of machine tooling by counting, its goal is to describe all processing courses with the unified norm. Such new data interchange form has already been verified in allocating the SIEMENS , FIDIA and European OSACA-NC numerical control at present.2 pairs of basic estimations of technology and industry development of numerical control of our countryThe technology of numerical control of our country started in 1958, the development course in the past 50 years can roughly be divided into 3 stages:The first stage is from 1958 to 1979, namely closed developing stage. In this stages, because technology of foreign countries blockade and basic restriction of terms of our country, the development of numerical control technology is comparatively slow.The second stage is during " Sixth Five-Year Plan Period " , " the Seventh Five-Year Plan Period " of the country in second stage and earlier stage in " the Eighth Five-Year Plan Period ", namely introduce technology, digest and assimilate, the stage of establishing the system of production domesticization arisesing tentatively. At this stage , because of reform and opening-up and national attention , and study the improvement of the development environment and international environment, research , development and all making considerable progress in production domesticization of the products of the technology of numerical control of our country.The third stage is during the " Ninth Five-Year Plan Period " on the later stage in " the Eighth Five-Year Plan Period " of the country, namely implement the research of industrialization, enter market competition stage. At this stage , madesubstantive progress in industrialization of the domestic numerical control equipment of our country. In latter stage for " the Ninth Five-Year Plan ", the domestic occupation rate of market of the domestic numerical control lathe is up to 50%, it is up to 10% too to mix the domestic numerical control system (popular ).Make a general survey of the development course in the past 50 years of technology of numerical control of our country, especially through tackling key problems of 4 Five-Year Plans, all in all has made following achievements.a.Have establish the foundation of the technical development of numerical control, has mastered modern numerical control technology basically. Our country has already, the numerical control host computer , basic technology of special plane and fittings grasped and driven from the numerical control system and servoly basically now, among them most technology have already possessed and commercialized the foundation developed , some technology has already, industrialization commercialized.b.Have formed the industrial base of numerical control tentatively. In tackling key problems the foundation that the achievement and some technology commercialize , set up the systematic factories of numerical control with production capacity in batches such as numerical control in Central China , numerical control of the spaceflight etc.. Electrical machinery plant of Lanzhou, such factory and the first machine tool plant of Beijing , the first machine tool plant of Jinan ,etc. several numerical control host computer factories of a batch of servo systems and servo electrical machineries as the numerical control in Central China,etc.. These factories have formed the numerical control industrial base of our country basically.c.Have set up a numerical control research, development , managerial talents basic team . Though has made considerable progress in research and development and industrialization of numerical control technology, but we will realize soberly, the research and development of the technology of advanced numerical control of our country, especially there is greater disparity in current situation and current demand of our country of engineering level in industrialization. Though very fast from watching the development of our country vertically, have disparity horizontally more than (compare foreign countries with ) not merely engineering level, there is disparity too in development speed in some aspects, namely the engineering level disparity between some high-grade , precision and advanced numerical control equipment has the tendency to expand .Watch from world , estimate roughly as follows about the engineering level of numerical control of our country and industrialization level.a.On the engineering level, in probably backward 10- 1 years with the advanced level in foreign countries, it is bigger in high-quality precision and sophisticated technology.b.On the industrialization level, the occupation rate of market is low, the variety coverage rate is little, have not formed the large-scale production yet; The specialized level of production of function part and ability of forming a complete set are relatively low; Appearance quality is relatively poor; Dependability is not high, the commercialized degree is insufficient; Ones own brand effect that the domestic numerical control system has not been set up yet, users have insufficient confidence.c.On the ability of sustainable development, research and development of numerical control technology , project ability are relatively weak to the competition; It is not strong that the technological application of numerical control expands dynamics;Research , formulation that relevant standards are normal lag behind. It is analysed that the main reason for having above-mentioned disparity has the following several respect.a.Realize the respect. Know to industrys process arduousness , complexity and long-term characteristic of domestic numerical control insufficiently; It is difficult to underestimate to add strangling , system ,etc. to the unstandard , foreign blockade of the market; It is not enough to analyse to the technological application level and ability of numerical control of our country.b.System. Pay close attention to numerical control industrialization many in the issue , consider numerical control industrialization little in the issue synthetically in terms of the systematic one , industry chain in terms of technology; Have not set up related system , perfect training , service network of intact high quality ,etc. and supported the system.c.Mechanism. It causes the brain drain, restraining technology and technological route from innovating again , products innovation that the bad machine is made, and has restricted the effective implementation of planning , has often planned the ideal , implement the difficulty.d.Technology. The autonomous innovation in technology of enterprises is indifferent, the project of key technology is indifferent. The standard of the lathe lags behind, the level is relatively low, it is not enough for new standard of the numerical control system to study.3 pairs of strategic thinking of technology and industrialized development of numerical control of our country 3.1 Strategic considerationOur country make big country, industry is it is it accept front instead of transformation of back end to try ones best to want in shifting in world, namely should master and make key technology advancedly, otherwise in a new round ofinternational industrial structure adjustment, the manufacturing industry of our country will step forward and " leave the core spaces ". We regard resource , environment , market as the cost, it is only an international " machining center " in the new economic pattern of the world to exchange the possibility got and " assemble the centre ", but not master the position of the manufacturing center of key technology , will so influence the development process of the modern manufacturing industry of our country seriously. We should stand in the height of national security strategy paying attention to numerical control technology and industrys question , at first seen from social safety, because manufacturing industry whether our country obtain employment most populous trade, the development of manufacturing industry not only can improve the peoples living standard but also can alleviate the pressure of employment of our country , ensure the stability of the society; Secondly seen from national defence security, the western developed country has classified all the high-grade , precision and advanced numerical control products as the strategic materials of the country, realizing the embargo and restriction to our country, " Toshiba incident " and " Cox Report " is the best illustration.3.2 Development tacticsProceed from the angles of the fundamental realities of the country of our country, regard the strategic demand of the country and market demand of national economy as the direction, regard improving our country and making the comprehensive competitive power of equiping industry and industrialization level as the goal, use the systematic method , be able to choose to make key technology upgraded in development of equiping industry and support technology supporting the development of industrialization in our country in initial stage of 21st century in leading factor, the ability to supply the necessary technology realizes making the jumping development of the equiping industry as the content of research and development.Emphasize market demand is a direction, namely take terminal products of numerical control as the core, with the complete machine (Such as the numerical control lathe having a large capacity and a wide range, milling machine , high speed high precise high-performance numerical control lathe , digitized machinery of model , key industry key equipment ,etc.) drive the development of the numerical control industry. Solve the numerical control system and relevant functions part especially The dependability that (digitized servo system and electrical machinery , high speed electric main shaft system and new-style enclosure that equip ,etc. ) and production scale question. There are no products that scale will not have high dependability ; Will not have cheap and products rich in the competitiveness without scale ; Certainly, it is difficult to have day holding up ones head finally that there is no scale Chinese numerical control equipment.In equiping researching and developing high-grade , precision and advancedly , should emphasize the production, learning and research and close combination of the end user, regard " drawing, using, selling " as the goal, tackle key problemsaccording to the national will, in order to solve the needing badly of the country. Numerical control technology, emphasized innovation, put emphasis on researching and developing the technology and products with independent intellectual property right before the competition, establish the foundation for the industry of numerical control of our country , sustainable development of equipment manufacture and even the whole manufacturing industry.List of references:[1]China machine tool industrial association Development department of the trade.
