摘　　要：零件信息模型对计算机辅助工艺规划(CAPP)系统的可靠性和质量具有决定性作用.针对CAD/CAPP信息集成困难的问题,根据特征事物元理论,提出了一种基于特征事物元的计算机辅助工艺零件信息模型.采用对象技术,用Visual C++语言,在Pro/ENGINEER系统中实现了零件信息模型的建立、识别与获取(extraction),最终实现了CAD/CAPP信息的高效集成.最后,通过实例证明了该方法的正确性和有效性.The part information model is definitive to the reliability and quality of computer-aided processing planning（CAPP） system.In order to overcome the difficult integration problem of CAD and CAPP,a CAPP part information model based on feature matter-affair-element is carried out.The foundation,identification and extraction of part information model in Pro/ENGINEER system with the object technology and Visual C＋＋ language are achieved and the efficient integration of CAD and CAPP information is actualized.In the end,the correctness and validity of this method is testified by an example.
