Machining Process Knowledge Discovery Technology:on the Basis of MBD Process model

摘要：

　　To tackle process knowledge discovery difficulty in machining process,this paper studies knowledge discovery method of 2.5-dimensional machining characteristics based on process model with model based definition technology,and finds out machining process design knowledge with the natural structured process description ability of MBD process model.Firstly,the composition of machining geometry ontology and process ontology is analyzed.Secondly,decision tree between ontology are obtained by analyzing abundant samples of MBD process model.Thus,the process and method of reasoning from geometry ontology to process ontology is achieved.Finally,the validity of process knowledge discovery method is exemplified with a group of MBD process models.
