1、Lesson 65 Computer Aided Process PlanningTerminologyText tour 8/5/20221机械工程专业英语教程Terminology8/5/20222机械工程专业英语教程Clerical Of or relating to clerks or office workers or their work.办事员的，职员的，文书的：职员、办公室人员或其工作的或与之相关的Concomitant 1. Occurring or existing concurrently 伴随的：同时发生或共存的2. One that occurs or exists

2、concurrently with another伴随物：与另一个同时发生或共存的事物机械工程专业英语教程8/5/2022Algorithm A step-by-step problem-solving procedure, especially an established computational procedure for solving a problem in a finite number of steps算法，规则系统：一种循序渐进解决问题的过程，尤指一种为在有限步骤内解决问题而建立的计算过程 3According to the Tool & Manufacturing Eng

3、ineers Handbook, process planning is the systematic determination of the methods by which a product is to be manufactured economically and competitively. It essentially involves selection, calculation, and documentation. Processes, machines, tools, operations, and sequences must be selected. Such fa

4、ctors as feeds, speeds, tolerances, dimensions, and costs must be calculated.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。它主要由选择、计算和建立工艺文件组成。对加工方法、机床、刀具、工序和顺序必须进行选择。对于一些参数如进给量、速度、公差、尺寸和成本等应该进行计算。机械工程专业英语教程8/5/2022Text tour4Most manufacturing engineers would agree that, if ten different planners wer

5、e asked to develop a process plan for the same part, they would probably come up with ten different plans. Obviously, all these plans cannot reflect the most efficient manufacturing methods, and, in fact, there is no guarantee that any one of them will constitute the optimum method for manufacturing

6、 the part.大部分制造工程师都会同意这个看法，即如果10个不同的工艺人员进行同一个零件的工艺设计，他们很可能得出10种不同的方案。显然，并不是所有这些方案都不能反映最适当的制造方法，而且，事实上也不能保证它们中的任何一个方案是由加工这个零件的最好的方法组成的。 机械工程专业英语教程8/5/20225A planner must manage and retrieve a great deal of data and many documents, including established standards, machinability data, machine specifica

7、tions, tooling inventories, stock availability, and existing process plans. This is primarily an information-handling job, and the computer is an ideal companion.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：已经建立了的标准、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。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。 机械工程专业英语教程8/5/20226Most imp

8、ortant for CIM, computer-aided process planning produces 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的数据，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。机械工程专业英语教

9、程8/5/20227In the variant approach, a set of standard process plans is established for all the parts families that have been identified through group technology. The standard plans are stored in computer memory and retrieved for new parts according to their family identification. 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 jo
