3. Get ready to speak on the following problems using the word combinations

1. Since about 1970 there has been a new trend toward the use of computers

( to perform many of the functions, computers, can, design and production, be related to, the technology, this trend, be associated with, be called CAD/CAM, CAD/CAM technology, be based on the capability of a computer system, to process, store, and display large amounts of data, it, to be applied, in many industries, CAD/CAM, to assist in the automation of the manufacturing operations, and, in the automation of the design procedure).

2. Computer-aided design (CAD) uses computer systems in the creation, modification, analysis, and optimization of a design ( the designer, to work with the CAD system , the traditional drafting board, rather than, he, to create, to store, the lines and surfaces that form the object, in the computer database, then, to be generated, the detailed drawings, CAD technology, to represent, three-dimensional modeling techniques, for drafting and manipulating solid objects on the screen).

3. Computer-aided process planning (CAPP) systems select sequences of operations and machining conditions (models of the manufacturing system, to be simulated, can, by computers, before, they, to be built)

4 Computer-aided manufacfacturing (CAM) uses computer systems to assist in the planning, control, and management of production operations ( the basic manufacturing functions,machining, forming, joining, assembly, and inspection,to be supported, by CAM systems, tyere to be, either or, direct, indirect connections between the computer and production operations, dpending on, in the factory, whether, the computer, to be used, to monitor or control, the production processes).

5. Computer-integrated manufacturing (CIM) includes all the engineering functions of CAD/CAM and also the business functions of the firm( in an ideal CIM system, computer technology, to be applied to, all the operational and information-processing functions, of the company, from customer orders through design and production, to product shipment,customer service,and, CIM, to represent, the highest level, in, of, automation, manufacturing)

4. Speak on:

1. The role of computers in CAD/CAM technology,

2. CAD technology,

3. CAM technology,

4. CIM system.
