结合杭州叉车总厂ＨＣ—ＣＡＰＰ工程应用项目，构造了一种基于知识推理的创成式ＣＡＰＰ专家系统模型。原型系统中，工艺设计、机床选择、刀具选择、夹具等知识库的管理独立于推理机，不仅为知识库管理、推理机改进、零件特征排序、知识库系统移植等提供方便，而且系统采用ＲＤＢ（关系型数据库管理）技术、ＯＤＢＣ（开放式数据库互连）技术，为ＣＡＰＰ、ＣＡＤ、ＮＣＰ（数控编程）子系统内部不同模式数据交换提供接口。
Combined with HC-CAPP engineering project of Hangzhou Forklift Truck Factory, a creative CAPP expert system model based on knowledge reasoning was constructed. In the prototype system, the management of knowledge base such as process design, machine tool selection, tool selection and fixture is independent of reasoning machine, which not only facilitates the management of knowledge base, improvement of reasoning machine, ordering of parts features, transplant of knowledge base system, (Relational Database Management) technology, ODBC (Open Database Interconnection) technology to provide interfaces for different modes of data exchange within CAPP, CAD, NCP (Numerical Control Programming) subsystems.
