Chapter 5 The Computers Applications in Industry

Lesson 5.1 CAD/CAM A key goal of CAD/CAM (Figure 5-1) is to produce data can be used in manufacturing a product while developing the database for the design of that product. Figure 5-1 The block diagram of a CAD/CAM system Chapter 5 The Computers Applications in Industry

Lesson 5.1 CAD/CAM Chapter 5 The Computers Applications in Industry Since the advent of CAD/CAM, other terms have developed: (1) Computer-aided design and manufacturing (CAD/CAM). (2) Computer-aided engineering (CAE). (3) Computer graphics (CG). (5) Computer-aided design and drafting (CADD). (4) Computer-aided process planning (CAPP).

Lesson 5.1 CAD/CAM Chapter 5 The Computers Applications in Industry These spin-off terms all refer to specific aspects of the CAD/ CAM concept. Interactive computer graphics (ICG) plays an important role in CAD/CAM. The applications of CAD/CAM can continually improve a companys productivity, and competitiveness.

CAD/CAM Lesson 5.1 CAD/CAM Chapter 5 The Computers Applications in Industry Notes [1] When the database is successfully implemented, CAD/CAM should remove the wall that has traditionally existed between the design and manufacturing components. CAD/CAM involves the sharing of a common database between the design and manufacturing components.

Lesson 5.1 CAD/CAM Chapter 5 The Computers Applications in Industry Notes [2] Through the use of ICG, designer develop a graphic image of the product being designed while storing the data that electronically make up the graphic image.

CAD/CAM Lesson 5.1 CAD/CAM Chapter 5 The Computers Applications in Industry Notes [3] The rational for CAD/CAM are: increased productivity; better quality; better communication; common database with manufacturing; reduced prototype construction costs; faster response to customers.

CAM Chapter 5 The Computers Applications in Industry Lesson 5.2 CAD/CAMs Applications Notes [1] Part programming software is incorporated into a family of CAM software and has a dynamic graphics database to hold the actual machining sequences. These sequences can be viewed, edited, chained, or deleted.

CAD/CAM Chapter 5 The Computers Applications in Industry Lesson 5.2 CAD/CAMs Applications Notes [2] When a part program is generated using a CAD/CAM system, a solid model may be used to generate a realistic picture of the workpiece, the tools, the cutter path and the finished part.

Chapter 5 The Computers Applications in Industry Lesson 5.2 CAD/CAMs Applications through...language process planning Notes [3] Process planning, through which design information can be translated into manufacturing language, is the critical bridge between design and manufacturing.

CAD Chapter 5 The Computers Applications in Industry Lesson 5.2 CAD/CAMs Applications Notes [4] The bills of materials can come directly from the CAD system, which include the stock number, name of item, quantity in stock, unit of measure, minimum stock level, lead time of purchased or manufactured in-house, and the specifications of each component part and suppliers.
