Computer Aided Generation the Assembly Process Files for Virtual Assembly

Computer Aided Assembly Process Planning is a method of automatically generating assembly process files with computer. This paper describes an integrated assembly process files generation system for virtual assembly. The objectives of this study are to integrate assembly planning of a product with its CAD model, generate a correct and practical assembly sequence and establish a software system to generate the assembly process files. The method of generating assembly process charts for virtual assmbly is researched. The system framework of generating assembly process charts is been set up. The assembly model information that needed for the assembly process charts generation is analyzed. The expression method of assembly sequence and arithmetic of generating assembly process charts is put forward. A speed reducer is used as an example to check the system.
