By analyzing the reinforced sheet parts on a certain engine, the developed dimension is determined by calculation and related software. The working parts of cavity and punch dies for bending deforming were designed by CAE, and Mastercam is used to simulate their machining. The milling cutters and the parameters should be reasonably selected to achieve the optimal cutter moving route. Finally, the 2D video of their machining process with details were obtained and meantime the assembly dra...
