Research on approach of part process case reusing based on ontology mapping
基于本体映射的零件工艺实例重用方法研究*

Aiming at case-based similarity reusing in computer aided process planning(CAPP),to resolve this problem,this paper proposed method of part process case reusing based on ontology mapping.Firstly,constructed a new part process ontology and part process case ontology of the library by analysis of the part case’s information.Then,based on ontology mapping method,completed the retrieval and reusing of new part process case by calculating the similarity among concepts.Finally,presented an example of shaft parts to illustrate the effectiveness of this method.
