摘要
提出了一种新的基于实例与知识的混合推理策略。它既可通过对已存在的实例零件的工艺进行变异设计来获得当前零件的工艺,也可根据工艺知识库中的知识进行创成设计。介绍了基于实例与知识的CAPP系统的总体结构,给出了实例与知识的表达方式,并详细讨论了基于实例和基于知识两种推理的实现过程。
The reasoning strategy is one ofthemost important factors anecting the performance ofa CAPP system. A new hybrid reasoning strategy based on case and knowledge is proposed.The process planning of a part can be obtained through the variation of that of a practicalcase already existing,or it may be carried out with the creation based on the knowledge inthe knowledge base. The overall structure of the CAPP system based on the case and knowl-edge approach is presented and the representation of case and knowledge as well as the real-ization of two such kinds of reasoning are discussed.
