Digital Modeling Method for 3D Assembly Process Planning Model.

In order to design the assembly process plan based on the 3D model, the digital modeling method for 3D assembly process planning model was studied. Firstly, the process of assembly process planning was divided into two stages, such as the stage for rough assembly process planning and the stage for complete assembly process planning. According the different stages of the assembly process planning, three kinds of assembly process planning model were proposed, namely the disassembly process planning model, rough assembly process planning model and complete assembly process planning model. The representation method for the above three kinds of model and the auxiliary assembly process information was given, the mapping mechanism for them was proposed. Finally, based on the above modeling method, an assembly process planning system based on 3D model was developed, and 3D assembly process plan for an engine model was designed using the system.
