1、Lesson 50 The Roles of Engineers in ManufacturingTerminologyText tour 8/5/20221機械工程專業(yè)英語教程Terminology8/5/20222機械工程專業(yè)英語教程Interdependent Mutually dependent相互依賴的, 互相依存的Data base A collection of data arranged for ease and speed of search and retrieval. 數(shù)據(jù)庫：為進行快速簡便查找和檢索而組織的數(shù)據(jù)集合機械工程專業(yè)英語教程8/5/2022Overload 1

2、. To load too heavily使超載，使過載2. An excessive load過重的負擔 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.許多工程師的職責是進行產(chǎn)品設計，而產(chǎn)品是通過對材料的加工制造而生產(chǎn)出來的。設計工程師在材料選擇、制造方法等方面起著關(guān)鍵的作用。一個設計工程師應該比其他的人更清楚地知道他的設計需要達到什么目的。機械工程專業(yè)英語教程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. 一些工程師進行專用工藝裝備的設計，以使通用機床能夠被用來生產(chǎn)特定的產(chǎn)品。這些工程師們在機床、工藝能力和材料方面必須具有廣泛的知識，以使機器在沒有過載和損壞，而且對被加工材料沒有不良影響的情況下，更為有效地完成所需要的加工工序。機械工程專業(yè)英語教程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.盡管工程師們所起的作用可能會有很大差別，但是，大部分工程師們都必須考慮材料與制造工藝之

7、間的相互關(guān)系。低成本制造并不是自動產(chǎn)生的。在產(chǎn)品設計、材料選擇、加工方法和設備的選擇，工藝裝備選擇和設計之間都有著非常密切的相互依賴關(guān)系。機械工程專業(yè)英語教程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).隨著計算機和由計算機控制的機器的出現(xiàn)，我們進入了一個生產(chǎn)計劃的新時代。采用計算機將產(chǎn)品的設計功能與制造功能集成，被稱為CAD/CAM(計算機輔助設計/計算機輔助制造)。機械工程專業(yè)英語教程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
