and manufacturing, two activities which have traditionally been treated as distinct

and separate functions in a production firm. Ultimately, CAD/CAM will provide the

technology base for the computer-intgrated factory of the future.

Computer-aided design(CAD) can be defined as the use of computer systems to

application programs include

例如，这些应用程序包括应力应变分析组件，动态反应机制，热传递计算，和数

控编程的一部分。该应用程序的内容将会随着企业用户的不同而变化，这是因为

他们的生产线，生产工艺和消费者市场不同。这些因素导致对cad系统要求的不

stress-strain analysis of components, dynamic response of mechanisms, heat-transfer

calculations,and numerical control part programming. The collection of application

programs will vary from one user firm to the next because their product lines,

manufacturing processes, and customer markets are different. These factors give rise

to differences in CAD system requirements.
