介绍了一种在ＣＡＰＰ专家系统中嵌入基于范例推理的方法；提出了工艺设计工作量最小的范例检索原则，并从工艺设计子任务相似的角度，给出了相似度的计算公式；分析了工艺设计实例与范例的区别，对范例管理进行了详细论述
A method based on case-based reasoning is introduced in the CAPP expert system. An example retrieval principle with the least process design workload is proposed. The calculation formula of similarity is given from the perspective of the similarity of process design sub-tasks. The difference between the design example and the example, discusses the example management in detail
