摘　　要：根据CAD/CAPP信息参数建立特征库,对基于STEP的集成系统进行特征造型。集成CAD基本几何数据和加工特征信息,使CAPP直接从CAD获取信息。该造型由特征库和特征管理器组成。用AutoCAD的AutoLisp进行二次开发,其工艺信息包括零件总体/加工面加工信息。The characteristic database was set up according to information parameter of CAD/CAPP, and characteristic model of integrated system based on STEP was established. The basic geometry data of CAD was integrated with the characteristic information of machining to make CAPP obtain information from CAD directly. The characteristic model consists of characteristic database and manager. The characteristic model was redeveloped by AutoLisp tool of AutoCAD, and technology information includes machining information of parts collectivity and machining surface.
