摘要
根据冲压零件的特点对零件的特征进行分类。在特征设计的基础上,建立特征间的定位关系图和联接关系图,采用合理的数据结构表达零件特征模型。将特征模型实例化为几何实体模型,从而实现基于特征设计的冲压零件的造型。
The feature of stamping part has been classi-fied by its character,on which figures of orientation relation and coupling relation have been created and a feature mod-el has been expressed using proper data structure.The fea-ture thodel has been instantiated via geometric solid,hence realization of modeling on feature design.
