基于加工意图的机加工艺知识重用方法研究

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.
