Abstract:In order to integrate the processes of computer aided assembly process planning and simulation in the large and complex product manufacturing such as an aircraft or a ship, etc,the concept of assembly process micro-planning(APMP) is proposed. By using APMP for information sharing and transferring between the area of process planning and process simulation, so the both is integrated. Besides, by using CAA to develop new function based on DELMIA,this technology is implemented. And the electro-assembly order and assembly process video can be output to guide the workers to implement a product assembly in a work shop.
