Multi-level Structuralized MBD Model for Manufacturing Reuse of Mechanical Parts

Due to lack of effective model representation, current MBD models cannot perform well in manufacturing reuse. In this paper, a new multilevel structuralized MBD model for manufacturing reuse is presented to capture the abstract information, topological information and machining semantic information involved. Firstly, the machining features considered as the machining semantic carriers are recognized from the MBD model. Then, the coupled machining feature cluster is introduced to construct the greater granularity structural elements than the machining features. Finally, the MBD model is structuralized by reorganizing the machining features and the coupled machining feature clusters in a hierarchical way. In the experiment, an aircraft structural part is utilized to verify our approach for manufacturing reuse.
