In
machining operations where heavy cuts are involved, top clamps alone may not be sufficient to restrain the workpiece. A workpiece stop may be used to prevent slippage of the part being machined (Figure 7.2).
Direct Mounting to the Table A large variety of milling clamps are available for direct table mounting of the workpiece. Always follow the rules of good clamping. Clamping studs or bolts should be fully screwed into their T-nuts. Clamp nuts should have full thread engagement on studs. Studs or clamp bolts should be located as close to the workpiece as possible and clamp support blocks arranged so that clamping pressure is applied to the workpiece (Figure7.1).

Workpieces can be easily distorted, broken, or otherwise damaged by excessive or improper clamping. One solution to this problem is to use a screw jack to support the workpiece (Figure 7.5). The jack should be placed directly under the clamp. Screw jacks are available in a variety of sizes and styles (Figure7.6). In lieu of a screw jack, solid blocks of the correct size may be used as both workpiece supports and clamp supports (Figure 7.7).

机器人的机械手完成机器人系统的具体工
作,它包括两个部分:机械部分和附属部分。 附属部分安装在机械手的基座上。基座固定在 工作现场的地板上。但有时基座也是可以移动 的,在这种情况下,基座安放在轨道上,用于 把机械手从一个位置移到另外的位置。
The appendage is the arm of the robot. It can be either a straight, movable arm or a jointed arm and gives the manipulator its various axes of motion. The jointed am is also known as an articulated arm. At the end of the arm, a wrist is connected. The wrist is made up of additional axes and a wrist flang. The wrist flang allows the robot user to connect different tooling to the wrist for different jobs.

Lesson 1 Basic Concepts in Mechanics1、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对运动、时间和作用力作出科学分析的分支称为力学。

它由静力学和动力学两部分组成。

2、Our intuitive concept of force includes such ideas as place of application, direction,and magnitudeand these are called the characteristics of a force.直观概念包括作用点、方向和大小。

这些称为力的要素3、Inertia is the property of mass that causes it to resist any effort to change its motion.惯性是质量所具有的抵抗任何外力改变其本身运动状态的性质.4、A particle is a body whose dimensions are so small that they may be neglected.当一个物体的尺寸特别小,可以忽略不计时,该物体可以被称为质点。

5、Law 1 If all the forces acting on a particle are balanced, the particle will either remain at rest or will continue to move in a straight line at a uniform velocity.第一定律如果作用在一个质点上的所有外力平衡,那么,这个质点保持原来的静止或者匀速直线运动状态不变。

第一课Text:It is known that metals are very important in our life. Metals have the greatest importance for industry. All machines and other engineering[7endVi5niEriN] constructions have metal[5metl] parts; some of them consist only 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 metalis 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 important nonferrous metal arecopper[5kCpE], aluminum[E5lju:minEm], lead[li:d], zinc[ziNk], tin[tin], but all these metals are used muchless than ferrous metals, because the ferrous metals are much cheaper.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。

Gear Broaching(拉齿)Gear broaching is not usually used for helical gears(斜齿轮)but is useful for internal spur gears(直齿轮 ); Setting up is lengthy because different dressing templates(砂轮修整样板)are needed if module, number of teeth, helix angle, or profile correction(齿廓修形量)are changed. Metal removal rates are high since no reciprocation of hob or workpiece(滚刀和工件)is required and so cutting speeds of 40 m/min can be used for conventional hobs(普通滚刀)and up to 150 m/min for carbide hobs(硬质合金滚刀). Annular gear 内齿轮, 齿圈(也称为internal gear) 小铁屑:用锉或剃等加工方法去除的细小金属屑。 ……Generation of a worm shape on the grinding wheel is a slow process(将砂轮展成为一个蜗杆形状是一个缓慢的过程since a dressing diamond(修整砂轮的金刚石)must not only form the rack profile but has to move axially as the wheel rotates. Metal removal rates are high since no reciprocation of hob or workpiece(滚刀和工件)is required and so cutting speeds of 40 m/min can be used for conventional hobs(普通滚刀)and up to 150 m/min for carbide hobs(硬质合金滚刀). This is the most popular method for high production rates with small gears(高效率的加工小齿轮).

Unit-7-Lathes-机电专业英语-图文课件
1.Engine Lathes [1]Engine lathes,of course,are general purpose
machines used in production and maintenance shops all over the world. Sizes range from small bench models to huge heavy duty pieces of equipment. Many of the larger lathes are equipped with auxiliary parts which are not commonly available in ordinary shops,such as automatic stops for the carriage.
Text & Translation
The first screw machines were designed to feed bar stock and wire used in making small screw parts. At present,however, the turret lathe is frequently used with a collet attachment,and the automatic screw machine can be equipped with a chuck to hold castings.
Text & Translation
In the single spindle automatic screw machine,a specific length of stock is automatically fed through the spindle to a machining area. At this point,the turret and cross slide move into position and automatically perform whatever operations are required. After the machined piece is cut off,stock is again fed into the machining area and the entire cycle is repeated.

考虑到最终形状中的材料是通过剪切从母体金属去除的,此区域传统上称为剪切区。 金属的实际分离始于屈服或断裂(视切削条件而定),从切削刀尖开始。然后变形金属(称 为切屑)流过刀具(前倾)面。如果刀具前倾面与切屑(变形金属)底面之间的摩擦相当大,那 么切屑进一步变形,这也叫做二次变形。滑过刀具前倾面的切屑被提升离开刀具,切屑 弯曲的结果被称为切屑卷。

机械工程英语 Unit 7 CAD CAM CAPP

机械工程英语 Unit 7 CAD CAM CAPP

Unit 7 CAD/CAM/CAPP计算机辅助设计/计算机辅助制造/计算机辅助工艺规划1.CAD/CAM是一个术语,意为计算机辅助设计和计算机辅助制造。

它是一种关于应用数字计算机在设计和生产中完成某些特定功能的技术。

这种技术正朝着设计和制造这两种传统上被生产工厂视为有区别的和分开的功能的活动高度集成的方向发展。

最终,CAD/CAM将为未来的计算机集成工厂提供技术基础。

2.计算机辅助设计(CAD)可定义为使用计算机系统来协助一个设计方案的形成、修改、分析和优化。

计算机系统由完成特定的用户公司要求的特别的设计功能的硬件和软件组成。

典型的CAD硬件包括计算机、一个或更多的图形显示终端、键盘以及其它外围设备。

CAD软件由完成系统的计算机图形处理的程序加上一些使用户公司的工程功能变得容易的应用程序组成。

这些应用程序的例子包括零件应力-应变分析,动态反应机制,热传递计算,以及数控零件编程。

从一个用户公司到下一个用户公司的应用程序的集合可能会有所不同,因为他们的生产线,制造工艺,和客户市场是不同的。

这些因素增加了CAD系统要求的不同。

3.计算机辅助制造(CAM)可以定义为通过计算机或直接或间接地介入工厂的生产资源,利用计算机系统计划、管理和控制生产车间的操作。

正如定义所说明的,计算机辅助制造的应用可分为以下两类:(1)计算机监视与控制。

这些是直接应用,为了监视和控制过程,计算机直接与生产过程相联系。

(2)生产辅助应用。

这些是间接应用,计算机用于辅助工厂里的生产作业,但计算机和制造过程之间没有直接界面。

提高绘图生产效率4.CAD/CAM系统需要一整套能提高生产效率的新的绘图基本原理。

例如,现在市场上的多数系统都有许多可以使新的有用的绘图技术自动化的内部功能。

比如层叠法,使绘图者能够以逻辑段的形式创建草图,逻辑段能分开储存以易于识别;但在一个单独零件中,这些逻辑段也可以马上被整体输出,说明整个图形。

这种方法类似于我们以前在生物课上见过的解剖图。

Lesson 7 Fasteners and Springs 紧固件和弹簧
Fasteners are devices which permit one part to be jointed to a second part and,hence,they are involved in almost all designs.The acceptability(满意程度)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:
• 弹簧: 一种弹性装置在被压缩和拉伸后仍能恢复原来的 形状。

3.Storage of energy.
Applications in this category are found in clocks, movie cameras(摄影机)and lawn mowers (割草机). Many parking meters (停车计时器) use spring mechanisms (弹簧机构)which perform the timing function. 4. Measurement of force. Scales (秤 ) used to weigh people is a very common application for this category.
