1、Lesson 50 The Roles of Engineers in ManufacturingTerminologyText 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Interdependent Mutually dependent相互依赖的, 互相依存的Data base A collection of data arranged for ease and speed of search and retrieval. 数据库：为进行快速简便查找和检索而组织的数据集合机械工程专业英语教程8/5/2022Overload 1

2、. To load too heavily使超载，使过载2. An excessive load过重的负担 3Many engineers have as their function the designing of products that are to be brought into reality through the processing or fabrication of materials. In this capacity they are a key factor in the material selection-manufacturing procedure. A d

3、esign engineer, better than any other person, should know what he or she wants a design to accomplish.许多工程师的职责是进行产品设计，而产品是通过对材料的加工制造而生产出来的。设计工程师在材料选择、制造方法等方面起着关键的作用。一个设计工程师应该比其他的人更清楚地知道他的设计需要达到什么目的。机械工程专业英语教程8/5/2022Text tour4Some design special tooling that is used so that standard machines can be

4、utilized in producing specific products. These engineers must have a broad knowledge of machine and process capabilities and of materials, so that desired operations can be done effectively and efficiently without overloading or damaging machines and without adversely affecting the materials being p

5、rocessed. 一些工程师进行专用工艺装备的设计，以使通用机床能够被用来生产特定的产品。这些工程师们在机床、工艺能力和材料方面必须具有广泛的知识，以使机器在没有过载和损坏，而且对被加工材料没有不良影响的情况下，更为有效地完成所需要的加工工序。机械工程专业英语教程8/5/20225Although their roles may be quite different, it is apparent that a large proportion of engineers must concern themselves with the interrelationship between ma

6、terials and manufacturing processes. Low-cost manufacture does not just happen. There is a close and interdependent relationship between the design of a product, selection of materials, selection of processes and equipment, and tooling selection and design.尽管工程师们所起的作用可能会有很大差别，但是，大部分工程师们都必须考虑材料与制造工艺之

7、间的相互关系。低成本制造并不是自动产生的。在产品设计、材料选择、加工方法和设备的选择，工艺装备选择和设计之间都有着非常密切的相互依赖关系。机械工程专业英语教程8/5/20226With the advent of computers and machines that can be controlled by computers or by the computers, we are entering a new era of production planning. The integration of the design function and the manufacturing fu

8、nction through the computer is called CAD/CAM (computer aided design/computer aided manufacturing).随着计算机和由计算机控制的机器的出现，我们进入了一个生产计划的新时代。采用计算机将产品的设计功能与制造功能集成，被称为CAD/CAM(计算机辅助设计/计算机辅助制造)。机械工程专业英语教程8/5/20227The design is used to determine the manufacturing process planning and the programming information for the manufacturing processes themselves. Detailed drawings can also be made from the central data base used for the design and manufacture, and programs can be ge
