摘要/Abstract

摘要： 为了解决目前工艺知识重用方法存在的问题，强化工艺知识重用时工艺员的主观能动性，满足工艺员对工艺知识的个性化、多元化需求，以MBD工序模型几何演变过程中蕴含的工艺知识为研究对象，提出基于加工意图的工艺知识重用方法。给出了加工意图的建模方法，加工意图的几何演变、工艺语义信息的捕捉方法以及加工意图的降维处理方法。提出多属性融合的加工意图与MBD工艺知识元的相似性加权评价方法，并进行了实例验证。

关键词: 工艺知识, 加工意图, 相似性度量, 知识重用

Abstract: In order to resolve the problems of current process knowledge reuse methods, strengthen the initiative and meet the personalized, diversified demands of crafts in the research of process knowledge reuse process, process knowledge contained in geometric evolution of MBD process model is as an object, process knowledge reuse method based on machining intent is proposed. Modeling methods, geometric evolution and process semantic information capture methods, dimensionality reduction method of machining intent are given. Finally, a integration of multi-attribute similarity measurement method between machining intent and MBD process knowledge unit is proposed, the example of verification is also given.

Key words: knowledge reuse, machining intent, process knowledge, similarity measurement
