将面向对象的知识表达方法应用于压铸模具的智能CAD系统中。将设计对象的属性、处理过程、启发性知识统一表示在对象结构中。模具设计的领域知识通过多重继承来实现。在知识系统的基础上完成了压铸模具的智能CAD系统设计。
The object-oriented knowledge expression was applied to design the CAD system of die casting die, in which the attributes, processing and heuristic knowledge of designed object were uniformly expressed by object structure. The domanial knowledge of die design are organized through multi-ply inheritage. Based on the knowledge system, an intelligent CAD system has been developed.
