| Abstract: | Obtaining assembly mating constraints has significance in many different fields such as assembly design and assembly planning. The existing acquisition methods could induce the mating constraints being omitted or invalid. We researched on the method of automatic acquisition assembly mating constraints. Based on the geometry and topology information of CAD model, a novel algorithm integrating recognizing the geometrical constraints and validating to obtaining assembly mating constraints is presented. Experimental results show that this approach can remarkably improve the acquisition efficiency, correctness and validity of constraints. |
