Abstract
To deal with low efficiency and veracity of the automatic geometry constraint recognition technology, a multi-layer automatic geometry constraint recognition algorithm was proposed. Multi-layer measurement schemes such as assembly intent acquisition, constraint precedence judge, constraint type attribute matching, constraint parameter matching, destination position matching and constraint validity checking were adopted to improve the automatic geometry constraint recognition's efficiency and veracity very well. The proposed algorithm have been verified in the self-developed system named Virtual Assembly Process Planning (VAPP) System, and this VAPP system has been applied in assembly process planning of aerospace products.
