ＣＡＤ／ＣＡＰＰ／ＧＡＭ是计算机集成制造系统中的关键环节，集中体现了物质流和信息流的集成。本文首先讨论ＣＡＤ／ＣＡＰＰ／ＣＡＭ系统开发的几种类型，然后对三个子系统进行功能分析，最后着重介绍了目前开发ＣＡＤ／ＣＡＰＰ／ＣＡＭ系统的重点技术，即并行工程哲理的运用和实现信息集成和共享的产品模型数据交换标准。
CAD / CAPP / GAM is a key part of the computer integrated manufacturing system, which embodies the integration of material flow and information flow. This article first discusses several types of CAD / CAPP / CAM system development, and then analyzes the functions of the three subsystems. Finally, the key technologies of CAD / CAPP / CAM system are introduced emphatically, that is, the application of concurrent engineering philosophy and the realization of information integration And shared product model data exchange standards.
