首先分析了冲模CAD体系结构的要求 ,并简要介绍了组件技术的特点。在对冲模设计任务分析及其层次化分解的基础上 ,论述了基于组件技术的冲裁模CAD系统设计方法 ,并给出了相应的实例。采用组件技术进行CAD系统开发 ,不但降低了应用开发的难度 ,也提高了系统的运行效率 ,使其具有复用性高、易于扩展、结构更加开放的特点 First of all, the requirements of die CAD architecture were analyzed and the characteristics of component technology were briefly introduced. Based on the analysis of die design task and its hierarchical decomposition, the design method of blanking die CAD system based on component technology is discussed and the corresponding examples are given. The development of CAD system using component technology not only reduces the difficulty of application development, but also improves the system operating efficiency, making it highly reusable, easy to expand, and the structure more open
