Study and System Extension on the Generation of Assembly Process Plan Sheet Based on UG

A type of architecture of a virtual assembly system was proposed.Based on this architecture,an integrated assembly model was introduced.The problem of information transmission between product structural parameters and dimensional parameters of it geometric model has been effectively solved in this system.Meanwhile the system has the functions of assembly process planning and simulation,the module of assembly process card can effectively generate the assembly process card which meeting the factory requirements. As a result,the virtual assembly system can significantly support the assembly process planning.
