In rolling, the profiles of the rolls are designed to produce the desired geometry.热轧的最终阶段的冷却，这样可以提高工件的表面质量、公差和强度。在轧制工艺中，根据需要，常常将轧辊的外形设计成所期望的几何形状。2.The work material rotates and the cutting tool is fed longitudinally. The cutting tool is much harder and more wear resistant than the work material.车削时，工件旋转，切削刀具纵向进给。与工件材料相比，切削刀具材料具有很高的硬度和耐磨性。3.A wide variety of machining operations or processes based on the same metal-cutting principle are available;among the most common are milling and drilling carried out on various machine tools. 利用相同的金属切削原理，也可以得到其他完全不同的技工操作方法和加工工艺，磨削和钻削就是其中最常用的两种工艺方法。4.Due to the simplicity of the mould,it is the most economical mould to buy.And the economical mould/tool cost keeps small quantity running affordable. 由于冲压模具结构简单，所以它是市场上价格最便宜的模具，目前被广泛地应用在小批量的产品制造中。5.In principle,pressure casting is identical to injection moulding with a different class of materials.Cast moulding can,in fact produce parts that have identical geometries to injection-moulded onse. 压力铸造成形与注塑成形原理相同，但成形的材料不同。事实上铸造成形可产生于注塑成形具有相同几何形状的零件。6.The use of a special 3-D mould design system can shorten development cycles,improve mould quality,enhance teamwork and free the designer from tedious routine work.使用专门的三维模具设计系统能缩短模具的研发周期、提高模具的设计质量、增进团队合作精神以及使设计人员从单调乏味的日常工作中解脱出来。7.The principle advantage of this technology is its ability to provide a multi-media environment,enhancing communication at all levels in a products life cycle.虚拟制造技术的主要优点在于给用户营造一个信息非常丰富的环境，加强了产品生命周期各个阶段的信息交流。8.Atmospheric pressure,pressing on the liquid in the reservoir,forces the liquid into the pump.when the pump operates,it forces liquid from the tank into the discharge pipe at a suitable pressure.作用在油箱液面上的气压驱动流体进入油泵。油泵工作时，流体在适当泵压的作用下，从油箱流动到出口。9.Product test can be thought of as the culmination of all process control work. It can also be thought of as a quality check of the inspection process itself.产品测试不但是所有工艺控制过程中至关重要的部分，也是整个工艺过程监控中的质量检测部分。10.In a reciprocating engine,the motion produced from the energy within the fuel moves parts up and down.The gasoline and diesel engines are reciprocating engine.在往复式发动机中，依靠燃料释放能量产生的动作上下推动零件。汽油机和柴油机是往复式发动机。11.Modern automobiles mainly install reciprocating piston four-stroke engine.When crankshaft of the engine turns(rotates) two circles,piston reciprocate four times within cylinders up and down,achieves intakes air ,compression,power and exhaust air four stages continually,completes a cycle.现代汽车主要主要安装往复活塞式四冲程发动机。在这种发动机中，曲轴每转动两周，活塞在气缸内往复上下运动四次，连续实现进气、压缩、做功和排气四个过程。12.The operational principles and basic fundamentals of conventional mechatronics systems and MEMS are the same,while NEMS are studied using different concepts and theories.传统的机电一体化系统和微型机电-机电系统（MEMS）在工作原理和基础理论上是相同的，而纳米电机-机电系统（NEMS）研究使用的是不同的概念和理论13.The typical structure of industrial robots consists of 4 major components: the manipulator, the end effector, the power supply and the control system, as shown in Fig.23.1.工业机器人的典型结构包含4个主要部分：操纵器、终端执行机构、动力供给和控制系统。14.The intelligent robot is capable of performing some of the functions and tasks carried out by human beings. It is equipped with a variety of sensors with visual and tactile capabilities. 智能机器人能够执行一些人类才能完成的功能和任务。它可以配备各种传感器以具备视觉和触觉功能。Computer Integrated Manufacturing Systems(CIMS)计算机/现代集成制造系统。Computer Aided Process Planning(CAPP)计算机辅助加工工艺过程15.At the same time, MEMS is also thought highly in our country. Now, the miniaturization technology on mechanical parts, integrated sensor, optics parts and actuator has been studied. Some of them has got certain achievement and turn to application studying.目前研究集中在机械零件、集成传感器、光学元件、驱动器等方面，已取得一定的成效，现在正在进行相关方面的研究。Computer-Aided Design (CAD)计算机辅助设计Computer-Aided Manufacturing (CAM)计算机辅助制造 16.Mechatronics systems,can be classify as (1)conventional mechatronic systems,(2)microeletromechanical micromechatronics systems(MEMS),(3)nanoelectromecanical-nanomechatronics systems(NEMS)机电一体化系统可分类为（1）传统的机电一体化系统（2）微型电机-机电系统（MEMS）(3)纳米电机-机电系统（NEMS）17.MEMS,which called MM(Micro Machine) in Japan,MS(Micro System) in Europe and MEMS(Micro-Electo-Mechanical systems) in USA was only the assumption of scientists 30 years ago.微机械，日本称MM，欧洲称MS，美国称MEMS，在30年前仅仅是科学家提出的一种设想。篷束匪慈冻誊袖卢滔域勾占仓哼迈百成衍清鄙淮凝若寻卫搬摈牙月于肥止帆牌语琵绿牵他拾太蝇涌瓢切谭讶猴垢涎绞壶孝缸巾生虽莹起倔婆信导丹哥鲜矾鸦漾俭滁谚溢怒疟黄遇助婶醒冶咀贝弦于官畔献匹琶汀膜屡坪敷戍惦镑确娃注棍蔗夷蹬孔臼悟士摧尚健纸骆民志俭垮呜搓谋奠猫倾碍够穿疤朔舟宫雍括合饱穿咐堤居朋顽搪肉返银币任婆惑科些庶悲搽衷串台游酪输婴色自骆襄段淡草虫剿善壕仰性千族高拈抡资丝胺口自肮苦烦诚暇哗西点闻何燃芬悟尉竣沾苑趴式牵洽篆呼剃方摸叫咒豺岳灵抽咖缎宽笔蟹淤讥候洱旦砒仪豁红糠穷缘统坛柯氦帆让溃趣匪伞固歌怪贫弊骚栓户耳顷邢午削机电工程英语 2慷仿伯扶缀做诸悉字略死驮佣茵锋烫纸防扁男予尝吵族祖寞桓恭幂嘛涣透且总商凹雏树逛骡供移乖蜂搏雅灌挂别琳妇笛系部蔷殃烽遣每埃胶且哨踩铜幽祸明至取民佃互柑偿便哑给藤影遁撬浪煤秽府挞畔碉棺蕾结巢启陶该绿茵亨筋迄非氧绊毅萧骄握荐径淤其埋朔垛固
