中文摘要：

分析了造成CAD／CAE／PDM系统集成困难的原因，介绍了基于Web服务面向服务的架构，根据模具设计、分析的具体任务要求和特点，提出使用Web服务架构进行CAD／CAE／PDM集成的方法，并给出了一个基于Web服务面向服务的广义模具CAD系统结构框架。

英文摘要：

The reason causing the difficulty in CAD/CAE/PDM integrating was studied. The service-oriented architecture （SOA） based on the web service was introduced. According to the special requirement and the characteristics of the die design and the analysis, a new approach for integrating CAD/CAE/PDM by adopting web services was presented. A service-oriented architecture of the generalized die CAD system was given based on web services.
