句子 第一单元 1，An engineering drawing usually contains two or three views(front,top,and side).Each view is an orthographic projiection of objects.工程图样一般含有2-3个视图(主视图，俯视图和侧视图)，每个视图均为所绘零件的正投影。

2.Features of sectional views are cutting-plane symbols,which show where imaginary cutting planes are paed to produce the sections.剖视图的特征是带有剖面线，剖面线符号表示利用想象的剖切面产生剖视图的位置。

3.Since the sdvent of well-developed interchangeable manufactire,these distances have been accompanied by tolerances of the plus-or-minus or min-and-max-limit types.由于互换性制造技术的出现和不断完善，零件图的尺寸都用带有正负公差或最大、最小极限的尺寸标注。

4.A proce flow schematic is a diagram commonly used in engineering to indicate the general flow of plant procees and equipment.工艺流程图常用来说明企业的生产工艺和设备流程。

5.In most cases the layout drawing ultimately becomes the primary source of information from which detail drawings and aembly drawings are prepared by other drafters under the guidance of the designer.在大多数情况下，设计人员绘制的总体布局图最终成为其他人员绘制零件图和装配图的第一手资料。

第五单元

1.The shaft rotates on rolling contact or bush bearings.Various types of retaining rings ,thrust bearings,grooves and steps in the shaft are used to take up axial loads and locate the rotating elements.传动轴一般用滚动或滑动轴承支承，用推力轴承、键槽、轴肩和定位环等为旋转零部件定位并且承受轴向载荷。

2.A solid shaft is obtainable commercially in round bar stock up to 15cm in diameter.It is produced by hot-drwing and cold-drawing or by machining-finishing with diametes in increments of 6mm or le.实心轴可利用直接购买的直径最大可达到15cm的棒料通过热拔，冷拔或机加工制成，轴的直径可由6mm或更小开始递增。

3.High speed spindles are designed with the spindle motor flanged to the spindle shaft,while conventional or normal spindles are mostly gear or belt driven.高速主轴一般通过法兰与主轴电动机连接，而普通主轴常常通过齿轮或传动带驱动。

4.The cold rolled shafts are stronger than hot rolled shafts but with higher residual strees.The residual stees may cause distortion of the shaft when it is machined,especially when slots or key ways are cut.冷轧加工的传动轴强度比热轧加工的高，但是会存在较大的残余应力。在对传动轴进行机加工特别是车槽或加工键槽时，残余应力的存在会导致轴发生挠曲变形。

5.Both the squarte and the rectangular keys are referred to as parsllel keys because the top,bottom and the sides of the keys are parallel.方键和矩形键都是平键，其上下左右侧面互相平行。6.Rigid couplings should be used only when the alignment of the two shafts can be maintained very accurately,not only at the time of installation but also during operation of the machines.刚性联轴器只能用于连接在安装和使用过程中对中性都有很好的两根传动轴。

第六单元

1.The main functions of lubricant system can not only cut down friction by coating moving parts with oil,but also produces a seal between the piston rings and the cylinder walls.润滑系统不但可以通过在运动零件上涂油而减小摩擦，还可以通过在活塞环和气缸壁之间储存机油，产生密封的作用。

2.The basic job of the suspension sysrem is to absorb the shocks caused by irregular road surfaces that would otherwise be transmitted to the vehicle and its occupants,thus helping to keep the vehicle on a controplled and level coures,regardle of road conditions.悬挂系统的基本功能是吸收不平坦路面引起的震动，否则该震动会被传递给车辆和乘坐人员。因此，悬挂系统有助于在各种路况下保持车辆可控并水平行驶。

第九单元

1：In summation,as the production volume increases,the combination of productivity gains and the ability to spread the setup cost over many parts makes CNC machining the obvious choice.总的来说，由于生产量增加，生产率提高，配置成本分散到众多部件上，数控加工成为显而易见的选择。

2：The pallet is a removable table on which the workpiece is mounted.After the workpiece has beeb machined,the workpiece adnd pallet are moved to a shuttle which then rotates,bringing a new pallet and a new workpiece into position for machining.托盘是一个可移动的平台，用来安装工件。工件加工完后，工件和托盘被移动到往复移动送件装置中轮转，将新的托盘和新的工件送至加工位置。

第十五单元

1：Some factors involved when considering a CIM implementation are the production volume,theexperience of the company or personnel to make the integration,the level of the integration into the product itself and the integration of the production procees.在考察计算机集成制造系统的实施情况时，会考虑这些因素：产量、企业或个人的集成经验、产品本身的集成水平和生产过程的集成水平。

2：Some studies askked managers how much their companies invest in several of the technologies that comprise CIM by measuring investment on a 7-point scale(1=noinvestment and 7=heavy investment).一些研究就企业在构成计算机集成制造系统的几项技术上的投资情况对其经营者进行了调查，并通过了7分制来衡量（1分=没有投资，7分=大力投资）。

第十六单元

1.The most widely accepted definition of an industrial robot is one developed by the robotic industries aociation An industrial robot is areprogrammable, multifunctional manipulator designed to move materials ,parts,tools,or,specialized

devices

through

variable programmed motions for the performance of a variety of tasks,in the context of general robotics, most types of industrial robots would fall into the category of robotic arms.最为广泛接受的工业机器人的定义是由机器人工人协会提出的，工业机器人是可重复编程，多功能的机械手，其设计目的是通过可改变的编程动作去移动材料，零件，工具或专用设备，来执行不同的任务。就常规的机器人技术而言，大部分类型的工业机器人都属于机械手的范畴。

2.It may be that when told to go to a certain x y z position that it gets only to within1mm of that position.This would be its accuracy which may be improved by calibration.But if that position is taught and teaching information is stored in controller memory and each time the robor is sent there it returns to within 0.1mm of the taught position then the repeatability will be within 0.1mm

当被指示要到达一个由xyz坐标确定的点时，它到达了距离该点0.1mm以内的位置，这就是精确度，精确度可以通过校正来改进。但是如果到了这个位置就示教并且示教信息被存贮与控制器的内存中，每次机器人都被送往哪里，它都会回到距离示教位置0.1mm以内的地方，则重复性就为0.1mm。

第二十一单元 The chais is an aembly of the frame, suspension , power train ,steering,and braking system,The automobile frame is usually made up of a number of square or box shaped steel members welded or riveted together to give the final shape which is strong enough to support the weight of the hody and other components.底盘由车架，悬挂系统，传动系统，转向系统和制动系统组成，车架通常由若干方钢或箱型钢构件焊接或铆接在一起形成，最终的轮廓有足够的强度来支撑车身和其他部件的重量。
