In order to form a type of bus rear side covering,the characteristics of the part was analyzed and then the 3D model was established.The stamping process was simulated by using CAE software Dynaform.The formability of the part was predicted and the die structure was optimized.The 3D model information was leading in MasterCAM software which NC milling tool path was designed and NC code was generated,then the milling process was simulated and verifyed based on the NC simulation system.The die surface was machined by inputing NC code in CNC machine which realized the integration of automobile panel design,analyse and manufacturing.
