4机械工程专业英语第四课
4机械工程专业英语第四课翻译的基本方法–增词与减词Skills of Translation –adding and reducing words三、增词与减词（一）增词译法:在对英文进行翻译时，若按字面翻译，句子的结构不完善，或句子的含义不明确，或词汇的概念不清晰时，需要增加某些词语，以便更完善、清楚地表达英语句子的内容。
例：Efficiency costs money, safety adds complexity, performanceincreases weight.直译：效率花费金钱，安全增加复杂性，性能增加重量。
增词译法：对设备(或器件)来说，要提高效率就要增加成本，要想保证安全势必要增加其复杂程度，而要改善性能就要增加其重量。
1. 增加表示时态的概念的词英语中表达时态的词往往是没有词义的，翻译时必须用一些中文词将其表达出来：Balloons were (and are) usually filled with hydrogen.气球过去（和现在）一般都用氢气来充气。
翻译的基本方法–增词与减词Skills of Translation –adding and reducing wordsWe can learn what we did not know.我们能够学会我们原来不懂的东西。
（过去时）The generator set will start working tomorrow.这台发电机组将于明天开始运行。
（将来时）An object is said to possess kinetic energy if it if moving.如果一个物体在运动，就可以说它有了动能。
（进行时）We have learned how to fit the computer.我们已经学会了怎样安装电脑。
（完成时）Reamers are used to finish drilled holes.绞刀用来将已经钻好了的孔进行精加工。

机械工程专业英语
Lesson11、the branch of scientific analysis, which deals with motions, time, and forces, is called mechanics and is made up of two parts, statics and dynamics. Statics deals with the analysis of stationary systems, i.e., those in which time is not a factor, and dynamics deals with systems, which change with time.对运动时间和作用力作出科学分析的分支成为力学.他由静力学和动力学两部分组成.静力学对静止系统进行分析,即在其中不考虑时间这个引述,动力学对事件而变化的系统进行分析.2、Any two such forces acting on a body constitutea couple. The arm of the couple is the perpendicular distance between their lines of action, and the plane of the couple is the plane containing the two lines of action.作用在一个刚体上的两个这样的的里构成一个力偶.力偶臂是这两个条作用线之间的垂直距离,力偶面是包含着两条作用线的平面.3、Mechanics deal with two kinds of quantities: scalars and vectors. Scalar quantities are those with which a magnitude alone is associated. Examples of scalar quantities in mechanics are time, volume, density, speed, energy, and mass. Vector quantities, on the other hand, possess direction as well as magnitude. Examples of vectors are displacement, velocity, acceleration, force, moment, and momentum.力学涉及两种类型的量,标量和矢量.标量是那些只有大小的量.在力学中标量的例子有时间、体积、密度、速率、、能量和质量.另一方面,矢量既有大小又有大小又有方向.矢量的例子有位移、速度、加速度、力、力矩、动量.Lesson2<此课后面没翻译,翻译的不太准确谅解>1 、The turning of a part in a lathe is another example of several forces in action.<as shown in figure1>车床车削是一些力在起作用的另一个例子.figure1〕如图〔.2 、If this workpiece is held between the centers of the lathe, the centers exert a compressive force against the work.如果这个工件在放在车床中心之间,中心车床对工作产生压力.3、 Rotary motion is required to drill holes, turn parts in a lathe, mill surfaces, or drive a generator or fan belt.扶轮运动需要去钻孔,在车床上转换两件,表面,或驱动发电机或风扇皮带4 、Harmonic and Intermittent Motion<谐和运动和间歇运动>: Any simple vibration, such as the regular back, and forth movement of the end of a pendulum, is simple harmonic motion.Lesson41 、Virtually all machines contain shafts. The most common shape for shafts is circular and the cross section can be either solid or hollow.实际上,几乎所有的机器中都装有轴.轴的最常见的形状是圆形,其截面可以是实心的,也可以是空心的<空心轴可以减轻重量>.有时也采用矩形轴,例如,螺丝起子的头部.套筒扳手和控制旋钮的杆.2、 A shaft must have adequate torisonal strength to transmit torque and not be over stressed it must also be torsional stiff enough so that one mounted component does not deviate excessively from its original angular position relative to a second component mounted on the same shaft.为了在传递扭矩时不发生过载,轴应该有适当的抗扭强度.轴还应该具有足够的抗扭强度,以使在同一轴上的两个传动零件之间的相对转角不会过大.3 、Components such as gears and pulleys are mounted on shafts by means of key. The design of the key and the corresponding keyway in the shaft must be properly evaluated. For example, stress concentrations occur in shafts due to keyways, and the material removed to from the keyway further weakens the shaft.齿轮和皮带轮等零件通过键连接在轴上.在键及轴上与之相对应的键槽的设计中,必须进行认真的计算.例如,轴上的键槽会引起应力集中,由于键槽的存在会使轴的横截面积减小,会进一步减弱轴的强度.4、Another important aspect of shaft design is the method of directly connecting one shaft to another. Devices such as rigid and flexible couplings accomplish this.轴的设计工作中的另一个重要方面是一根轴与另一根轴之间的直接连接方法.这是由刚性或者弹性联轴器来实现的.Lesson51、The term shaft usually refers to a relatively long member of round cross section that rotates and transmits power. One or more members such as gears ,sprockers,pullys,and cams are usually attached to the shaft by means of pins, keys,splines,snap rings,and other devices . Theselatter members are among the "associated parts" consedered in this text,as ate couplings and universal joints , which serve to connect the shaft to the source of power or load.2、It is apparent that shafts can be subjected to various combinations of axial,bending,and torsional loads,and that these loads may be static or fluctuating.3、Torsional defection can affect the accuracy ofa cam or gear driven mechanism .Furthermore,the greater the flexibility -either lateral or torsional-the lower the corresponding critical speed.4、A gear can be gripped axially between a shoulder on the shaft and a spacer ,with torque being transmitted through a keyways.Lesson71、Fasteners are devices which permit one part to be joined to a second part and ,hence,they are involved in almost all designs . The acceptability of any product depends not only on the selected components , but also on the means by which they are fastened together. The principal purposes of fasteners are to provide the following design features;紧固件是将一个零件与另一个零件进行连接的零件.因此,几乎在所有的设计中都要用到紧固件.人们对于任何产品的满意程度不仅取决于其组成部件,还取决于其连接方式.2、The importance of fasteners can be realized when referring ro any complex product,In the case of the automobile,there are literally thousands of parts which are fastened together to produce the total product.The failure or loosening of a single fastener could result in a simple nuisance such as a door rattle or in a serious situation such as a wheel coming off.Such possibilities must be taken into account in the selection of the type of fatener for the specific application.通过任何一个复杂的产品,都可以认识到紧固件在其中的重要性.以汽车为例,它是由数千个零件连接在一起而成为一辆车.一个紧固件的失效或松脱可能会带来像车门嘎嘎响这类小麻烦,也可能造成像车轮脱落这种严重的后果.因此,在为一个特定的用途选择紧固件时,应该考虑到上述各种可能性.Lesson81、Threaded fasterners perform the function of locating ,clamgping ,adjusting ,and transmiting force from one machine member to another .They are thoroughly standardized and generally designed for use in mass production of machines.2、 Matching external and internal threads so that they are may be assembled is the key to all thread fasteners.3、 A particular SAE grade specilication can be met by a number of different steels, thus faster manufacturers have some latitude in selecting the materials best suited to their specific production faclities.4、For moderate loads and speedes the correct selection of a standard of the bearing on the basis of load rating will usually secure satisfactory performance. 对于中等载荷和转速,根据额定负荷选择一个标准轴承,通常都可以保证其具有令人满意的工作性能.5、The deflection of less magnitude than that of the shafts or other components associated with the bearing .当载荷较大时,轴承零件的变形,尽管它通常小于轴和其它与轴承一起工作的零部件的变形,将会变得重要起来.Lesson91、Where speeds are high special cooling arrangements become necessary which may increase frictional drag .在转速高的场合需要有专门的冷却装置,而这可能会增大摩擦阻力.2、It is not surprising that ,owing to the high stresses involved,a predominant form of failure shouls be metal fatigue,and a good deal of work is currently in progress intended to improve the reliability of this type of bearing .滚动轴承由于在工作中会产生高的应力,其主要失效形式是金属疲劳,这一点并不奇怪,目前正在进行大量的工作以求改进这种轴承的可靠性.3、 The fit of the bearing races onto the shaft or onto the housing is of critical importance because of their combined effect on the internal clearance of the bearing as well as preserving the desired degree of interference fit.轴承套圈与轴或轴承座的的配合非常重要,因为它们之间的配合不仅应该保证所需要的过盈量,而且也应该保证轴承的内部间隙.4、The inner race is frequently located axially by abutting against a shoulder .Aradius at this point is essential for the avoidance of stressconcentration and ball races rae providede with a radius or chamfer to allow space for this .内圈通常是通过紧靠在轴肩上进行轴向定位的.轴肩出的圆弧半径主要是为了避免应力集中.在轴承内圈上加工出一个圆弧或者倒角,用来提供容纳轴肩处圆弧半径的空间.5、Where life is not the determing factor in design ,it is usual to determine maximum loading by the amount to which a bearing will deflect under load .在使用寿命不是设计中的决定因素的场合,通常根据轴承受载荷时产生的变形量来确定其最大载荷. Lesson131、One of the primary considerations in designing any machine or structure is that the strength must be sufficiently greater that the stress to assure both safety and reliability. To assure that mechanical parts do not fail in service, it is necessary to learn why they sometimes do fail. Then we shall be able to relate the stresses with the strengths to achieve safety.在设计任何机器或者结构时,所考虑的主要事项之一是其强度应该比它所承受的应力要大得多,以确保安全与可靠性.要保证机械零件在使用过程中不发生失效,就必须知道它们在某些时候会失效的原因,然后,才能将应力与强度联系起来,以确保其安全.2、Ideally, in designing any machine element, the engineer should have at his disposal the results of a great many strength tests of the particular material chosen. These tests should have been made on specimens having the same heat treatment, surface roughness, and size as the element he proposes to design, and the tests should be made under exactly the same loading conditions as the part will experience in service.设计任何机械零件的理想情况为,工程师可以利用大量的他所选用的这种材料的强度试验数据.这些试验应该在与所设计的零件有相同的热处理,表面粗糙度和尺寸大小的试件进行,而且试验应该在与零件使用过程中承受的载荷完全相同的情况下进行.3、Most hardness-testing systems employ a standard load which is applied to a ball or pyramid in contact with the material to be tested. The hardness is then expressed as a function of the size of the resulting indentation. This means that hardness is an easy property to measure, because the test is nondestructive and test specimens are not required. Usually the test can be conducted directly on an actual machine element.大多数硬度试验系统是将一个标准的载荷加在与被试验材料相接触的小球或者棱锥上.因此,硬度可以表示为所产生的压痕尺寸函数.这表明由于硬度是非破坏性试验,而且不需要专门的试件,因而硬度是一个容易测量的性能.通常可以直接在实际的机械零件上进行硬度试验.Lesson171、The first step in the manufacture of any product is design, which usually takes place in several distinct stages: 〕a〔conceptual; 〕b 〔 functional; 〕c〔 production design. During the conceptual design stage, the designer is concerned primarily with the functions the product is to fulfill.制造任何产品的第一步工作都是设计.设计通常可以分为几个明确的阶段；<a>概念设计；b 功能设计 c 生产设计.在概念设计阶段,设计者着重考虑产品应该具有的功能.2、Often a prototype or working model is made that can be tested to permit evaluation of the product as to function, reliability, appearance, serviceability, and so on.通常要制造出样机或着实物模型,并对其进行实验,评价产品的功能、可靠性、外观和维修保养性等3、As manufacturing progresses, it is inevitable that situations will arise that may require modifications of the materials being used. Experience may reveal that substitution of cheaper materials can be made.在制造过程中,不可避免地会出现对使用中的材料做一些更改的情况.经验表明,可以采用某些便宜材料作为代替.24/27课Working drawings are the drawings from which a design is implemented. All principles of orthographic projection and techniques of graphics can be used to communicate the details of a project in working drawings. A detail drawing is a working drawing of a single part 〕or detail〔 within the setof working drawings.工作图是将设计变为实际产品所依据的图样.所有的正投影原理和绘图技术都可以用来在工作图中表达一个项目中的细节.零件图是在一整套工作图中关于一个零件<或细节>的工作图.Title Blocks In practice, title blocks usually contain the title or part name, drafter, date, scale,company, and sheet number. Other information, such as tolerances, checkers, and materials, also may be given. Any modifications or changes added after the first version to improve the design is shown in the revisionblocks.标题栏在实践中,标题栏中通常包括标题或零件名称、制图员、日期、比例、公司和图号.另外,还可以包含公差、审核人员和材料等信息.在第一次制图之后,任何为了改进设计方案而作的修改和更正都应该在修改栏中标明.The allocation of proper production tolerances is therefore a most important task if the finished product is to achieve its intended purpose and yet be economical to produce. The size of the tolerances, as specified by the designer, depends on the many conditions pertaining to the design as well as on past experience with similar products if such experience is available.要使产品能够以较低的价格被生产出来并且能够满足设计的要求,规定适当的加工公差是最为重要的工作.公差的大小是由设计人员所确定的,它取决于许多与设计有关的条件以及过去在设计类似产品时所获得的经验<如果有这方面经验的话>.A part is said to be at the least material condition 〕LMC〔 when the dimensions are all at the limits that give a part with the smallest amount of material.当所有的尺寸都处在允许零件含有的材料量为最小的极限状态时,就称这个零件处于最小实体状态<LMC>.If the variations due to chance causes are too great, it is usually necessary to move the operation to more accurate equipment rather than spend more effort intrying to improve the process.如果随机原因对尺寸变化的影响过大,一般来说采用更精密的加工设备,要比花费更多精力来改变生产过程更为有效Lesson291、 The technique of dimensioning parts within a require range of variation to ensure interchangeability is called tolerancing. Each dimension is allowed a certain degree of variation within a specified zone ,or tolerance .for example, a part^s dimension might be expressed as 20+-0.50,which allows a tolerance 〕variation in size 〔 of 1.00 mm.给零件标注尺寸使其在一个规定的区间内变动,以保证他们具有互换性的技术称为公差技术.允许每个尺寸在规定范围内具有一定的变动量,称为公差.例如,一个零件的尺寸可以被表示成20+-0.50,其公差<尺寸变动量>为1.00mm.单词basic hole system 基孔制basic shaft system 基轴制Leesson331Engineering and technology students must became computer literate, to understand the applications of computer and their advantages. Not to do so will place students at a serious disadvantage in pursuing their careers.工程技术专业的学生们应该通晓计算机,了解计算机的用途和它们的优点.不这样做,就会使学生们在将来的职业生涯中处于非常不利的地位.2、Engineers generally agree that the computer does not change the nature of the design process but is a significant tool that improves efficiency and productivity工程师们通常认为计算机不会改变设计过程的性质.3、Computer of applications in engineering and other technical fields. Most graphical solutions that are possible with a pencil can be done on a computer and usually more productively. Applications vary from 3D modeling and finite element analysis to 2D drawings and mathematical caiculation.计算机图形学在工程技术领域的应用几乎没有任何限制,大部分可以铅笔完成的图解方法都可以用计算机完成,而且通常效率更高.其应用从建立三维模型和有限元分析,直到绘制平面图和进行数字计算.4、These systems offer many advantagees over traditional design and manufacturing systems, ineluding less design effort, more efficent material use, reduced lead tine, greater accuracy, and improved inventory controi.包括减少时间工作量,提高材料利用率,缩短产品研制周期,提高精度和改善库存管理.graphics has an aimost limitless numberLesson361、 engin lathes ,of course ,are general-purpose machines used in production and maintenance shops all over the world.普通车床是全世界的生产车间和维修车间里广泛使用的通用机床.2、 The tracer or duplicating lathe is designed to produce irregularly shaped parts automatically.靠模车床或仿形车床被设计用来对形状不规则的零件进行自动加工.3、machines with a wide variety of power accessories.Theprincipal feature of all turret lathes, however, is that the tools can perform a consecutive serials of operations in proper sequence. Once the tools have been set and adjusted ,little skill is required to turn out duplicate parts.高生产率的砖塔车床是装有许多动力附件的非常复杂的机器.然而,所有砖塔车床的主要特点是刀具能按适当顺序完成一系列的加工工序.一旦这些刀具被安装调整好后只只需要很低的技术就可以车削加工很多相同的零件.4、 The first screw machine were designed to feed bar stock and wire used in making small screw parts.单轴自动螺丝车床,顾名思义,一次仅能加工一根棒料.With the single spndle machine, the turret indexes around the spindle.在单轴车床上,砖塔围绕主轴转位.With a multiple spindle maching , however ,the spindle itself indexes.然而,在多轴自动车床上,主轴自己转位.6、 A vertical turret lathe is basically a turret lathe that has been stood on its headstock end.立式砖塔车床基本上就是将其从床头箱一端向下而竖立起来的一台砖塔车床.7、Many of today^s more sophisticated lathesare called machining centers since they arecapable of performing, in addition to thenormal turning operations, certain millingand drilling operations.当前许多技术更为先进的车床叫做加工中心.因为他们除了完成常规的车削工作之外,还可以完成某些铣削钻削工作单词：turret 砖塔,六角刀架,六角头general purpose 多方面的,多种用途的Lesson651.According to the Tool & Manufacturing English Handbook , process planning is the systematic determination of the methods by which a product is to be manufactured economically and competitively . 根据《工具与制造工程师手册》,工艺设计就是系统地确定能够经济地和有竞争力地将产品制造出来的方法.2.A planner must manage and retrieve a great deal of data and many documents , including established standards , machinability data ,machine specifications ,tooling inventories, stock availability ,and existing process plans.工艺人员应该管理和检索大量的数据和很多文件.其中包括已建立的标准,可加工性数据,机器的规格,工艺装备的清单,原材料库存量和一些目前正在应用的工艺文件.3.This is primarily an information-handing job ,andthe computer is an ideal companion.这主要是一些信息处理工作,而计算机是完成这项工作的一个理想助手.4.Most important for CIM ,computer-aided process machine readable data instead of handwritten plans . Such data can readily be transferred to other systems within the CIM hierarchy for use in planning.对计算机集成制造最为重要的是,计算机辅助工艺设计可以生成机器可以阅读数据,而不是手写的规程.这种数据可以传递到计算机集成制造体系中的另一个系统中,用以编制工艺规程.5.In the variant approach ,a set of standard processplans is established for all parts families thathave been identified through group technology.在派生法中,对采用成组技术确定的一个零件族中的所有零件,编制一套标准的加工工艺规程.6.Again ,GT helps to place the new part in an appropriate family .The standard plan is then edited to suit the specific requirements of a particular job.成组技术可以帮助把新零件归类于适当的零件族中.通过对标准工艺规程的编辑,可以满足对特定工作的专门要求.7.In the generative approach ,an attempt is made to synthesize each individual plan using appropriate algorithms that define the various technological decisions that must be made in the course of manufacturing.在创成法中,通过采用确定加工制造过程中各种工艺决策的适当算法,将各个单独的工艺规程综合起来.Lesson661、One of the most fundamental concepts in the areaof advanced manufacturing technologies is numerical control 〕NC〔.Prior to the advent of NC,all machine tools were manually operated and controlled .先进制造技术中的一个最基本的概念是数字控制<NC>.在数控技术出现之前,所有的机床都是有人工操作和控制的.2、Among the many limitations associated with manual control machine tolls, perhaps none is moreprominent than the limitation of operator skills .在与人工可控制的机床有关的很多局限性中,操作者的技术大概是最突出的问题.3、 Numerical control machines are more accurate than manually operated machines, they can produce parts more uniformly, they are faster, and the long-run tooling costs lower.数字控制的机器比人工操纵的机器的精度更高、生产零件的一致性更好、生产速度更快,而且长期的工艺装备成本更低.4 、The development of a concept known as direct numerical control 〕DNC〔solved the paper and plastic tape problems associated with numerical control by simply eliminating tape as the medium for carrying the programmed instructions.在形成直接数字控制〕DNC〔这个概念之后,可以不再采用纸带或塑料带作为编程指令的载体,这样就解决了与之有关的问题.5、The development of the microprocessor allowed for the development of programmable logic controllers 〕PLCs〔 and microcomputer.微处理器的发展为可编程逻辑控制器和微型计算机的发展做好了准备.6、These two technologies allowed for the development of computer numerical control 〕CNC 〔.这两种技术为计算机数控〕CNC〔的发展打下了基础.

4 Overview of Engineering Mechanics（工程力学概况）(1) Ideally, however, every such item has been designed according to some set of “functional requirements” as perceived by the designers-that is, it has been designed so as to answer the question, “E xactly what function should it perform?” In the world of engineering, the major function frequently is to support some type of loading due to weight, inertia, pressure, etc. From the beams in our homes to the wings of an airplane, there must be an appropriate melding of materials, dimensions, and fastenings to produce structures that will perform their functions reliably for a reasonable cost over a reasonable lifetime.然而，在理想的情况下，每一件产品都是设计人员根据对某些“功能要求”的理解而设计出来的，也就是说，在设计过程中，应该回答这样的问题，即“它应该具有哪种确切的功能？”在工程领域，主要功能通常是承受由于重力，惯性力，压力等作用的一些类型的载荷。
从我们居住房屋的梁到飞机机翼，都必须有一个适当的材料，尺寸，在较合理地寿命基础上具有较合理地成本，并能可靠地完成其功能的产品结构连接的组合。

In many companies cost estimating is accomplished by a professional who specializes in determining the cost of a component whether it's made in-house or purchased from an external source. This person must be as accurate as possible in his or her estimates, as major decisions about the product
are based on these costs.
在许多公司内部的成本估算是由一个专业人员来完成的。 他专门从事确定零件成本这项工作，无论这个零件是在 公司内部生产的，还是从其它公司购买的。因为对于产 品的决定主要是在这些估算的基础上做出的，所以这个
人必须尽可能精确地进行估算工作。

❖ One of the basic operations of hammer forging is the elongation of a piece of metal by stretching with hammer blows, causing it to become thinner and longer. 锤锻中常用开式模锻。在锤锻中零件通过锤击辅之以相对简单的 工具成型。其中包括开式锻模。锤锻的基本操作之一就是通过锤击使 金属伸长，促成其变细变长。
❖ Advantage：can produce components Байду номын сангаасf greater complexity and accuracy, with a better surface finish, than the more traditional methods not using closed dies. 优点：闭式模锻能生产高度复杂和精确的零件，而且表面光洁度要 比不用闭式锻模的更传统方法好。
它们均利用下落重量来产生金属成型所需的压力。锻造大零件则要 用到蒸汽、压缩空气、液压或电力驱动的锻压机。大型的自动化锻机用 于工程零件的批量生产。
open-die forging &closed-die forging 开式锻模和闭式锻模
1. open-die forging 开式锻模
❖ open-die forging, usually in the form of hammer forging.
Unit 4 Forging Processes
锻造工艺 What is Forging ？什么是锻造
➢It is an important hot-forming process. It is used in producing components of all shapes and sizes, from quite small items to large units weighing several tons. ➢It is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force. ➢One valuable feature of forging is that it improves the strength of the metal by refining the structure and making it uniform.
For example, the diameter of a bar can be increased by heating and hammering axially.
句意：例如，将棒料加热并进行轴向锤打，其直径即增大。
2. closed-die forging 闭式锻模
❖ It is very widely used for mass production in industry, in which the metal is shaped by pressing between a pair of forging dies. 闭式锻模在工业上广泛用于规模生产，金属在一对锻模之间挤压成型。
锻造是一种重要的热成型工艺。它能用于生产各种形状和尺寸、从很小到重 量数吨的零件。
在锻造过程中先将金属加热，然后施加合适的压力使其塑性变形。 锻造有价值的特性之一是它通过细化金属结构和使金属组织均匀而改善强度。
Forging tools 锻造工具
Hand forging tools comprise variously shaped hammers. 手工锻造工具包括各种不同形状的锤子。
❖ Makeup：The upper die is usually attached to the ram of a forging press or a forging hammer, while the lower die is stationary. Together they form a closed die. 组成：顶模通常放在锻压机的撞头或锻锤上，而底模则是固定的。 两者合在一起形成闭式锻模。
❖ Dies ： The dies are made of special heat-resistant and wearresistant tool steels. 模具：闭式锻模采用特殊的耐热、耐磨工具钢制成。
❖ Application：for the rapid production of large numbers of fairly small parts and very large components. For the latter ， e.g., modern jet-aircraft components ， giant hydraulically operated presses are used, which can develop forces of 50,000 tons and more. 应用：闭式模锻用于相当小的零件大批量快速生产，也可用于很大 的零件。对后者而言，例如现代喷气飞机零件，使用能产生50,000吨以 上压力的大型液压锻压机。
Forging Principle 锻造原理
they utilize the energy of a falling weight to develop the pressure needed for shaping the metal. Larger components are forged by means of forging presses operated by steam or compressed air or by hydraulic or electric power. Largely automatic forging machines are used for the quantity production of engineering parts.
