【摘要】 用结构分析与结构设计思想对离合器外壳冲压成型模具CAD／CAM系统进行了总体方案设计。采用IDEFO方法，分析建立了该系统的功能模型，阐述了其各主要模块的功能与实现机制，用IDEFIX方法给出了该系统信息模型中的一个实例，提出了用以描述系统信息传递的数据结构，并用Warnier图解加以表示。更多还原

【Abstract】 Ageneral scheme of a CAD/CAM system of forming dies for clutch housing starnping is accomplished with the structural analysis and structural design concept. In this paper the functional model for the system has been established by analysing with the IDEFO method,the functions and implementation of principal die segments are described. In addition,anactual example of information model in the system is cited with the IDEFIX methed and the data structure for describing the information transmission in the system is proposed and illustrated by the Warnier diag rams,更多还原
