根据模具设计知识的类型和特点，研究了ＣＢＲ系统中冲模结构知识库知识与控制性知识的表示方法，导出了符合工程设计习惯的冲模结构知识库知识表示方法—典型冲模结构特征图和与其对应的适合于ＣＢＲ推理的控制性知识表示方法—基于冲模结构特征的产生式规则表示。经开发的ＣＢＲ 系统使用，效果较为理想，为工程技术领域ＣＢＲ技术的应用提供了一个切实可行的方法
According to the type and characteristics of mold design knowledge, this paper studies the knowledge representation and control knowledge of die structure knowledge base in CBR system, and derives the knowledge representation method of die structure knowledge base which is in line with the engineering design habit - A Method of Representing Controlling Knowledge Suitable for CBR Inference - A Production Rule Representation Based on Die Structure Characteristics. The developed CBR system, the effect is more ideal for the engineering and technical CBR technology provides a practical method
