该文对基于PDM的CAD/CAPP/CAM的集成技术进行了研究。文章首先给出PDM的框架体系结构 ,随后提出CAD、CAPP、CAM与网络数据库交换数据的结构体系 ,最后给出了“信息反供给”的统一产品信息模型以实现系统的集成。
This paper studies the integration technology of CAD / CAPP / CAM based on PDM. The article first gives the frame structure of PDM, and then proposes the structural system of data exchange between CAD, CAPP, CAM and network database. Finally, a unified product information model of “information counter-supply” is given to realize the system integration.
