A MBD Procedure Model Based on Machining Process Knowledge

Linlin Liu, Rong Mo, Neng Wan


MBD technology has become an important technology to improve digital capability of product design and manufacture, but its application in machining process design is hindered by difficulty in creating MBD procedure model for failure to establish link between process knowledge and modeling knowledge. Firstly, this article analyzes the composition of machining process knowledge and MBD modeling knowledge as well as their relation. Then, modeling concept of positive MBD process model is proposed. After that, the decision tree for reasoning from process knowledge to modeling knowledge is summed up through large number of cases, and modeling operation knowledge converting process knowledge into 3D MBD process model is realized. In the end, the validity of MBD procedure model creating approach is exemplified.


MBD procedure model, decision tree, process ontology, reversed creation method.
