摘　　要：为解决数控加工CAD/CAPP/CAM系统中零件设计和制造的信息处理与传递问题,将零件按结构分类并将同类零件的设计和制造信息定义为设计特征、管理特征、工艺特征,借助CAD/CAM软件二次开发平台,采用交互式参数化设计方法进行特征识别来构造零件设计模型、管理模型、数控加工模型,从而建立CAD/CAPP/CAM系统关键的同类零件图形数据库.In order to solve the information handling and transmission problems of part design and manufacturing in CAD/CAPP/CAM system of NC machining, the parts are classified according to structure and the design and manufacturing information of the same kind parts are defined as design character, craft character. By means of second-development platform of CAD/CAPP/CAM, using feature recognition method by interactive parametric design method, the parts design model, management model, NC machining model are built, so the key same king parts graphic database based on CAD/CAPP/CAM is built.
