| Abstract: | Auto-extracting of the constraint face information of parts is an important issue of virtual assembly. It presents a new approach of determining constraint faces of parts effectively, designs a new algorithm which may recognize constraint surfaces of parts and extracts automatically the constraint surfaces parameters. The example shows that the approach can meet the needs of assembly process planning and improve the efficiency of constraint recognition effectively. |
