It is the most important to improve the efficiency in the production management and shorten the cycle in the R&D stage for the purpose of the advantage in the pre-market competition. In recent years, the industry generally applied the simulation analysis of finite element method for the forging process to obtain the information between the mold and the forging. As many of the parameters and simulation cycles, the simulations prolong the R&D stage and the products lag behind in the market rival. In this study, we discussed the leading process parameters with the professional engineers by the application of Taguchi method and then selected the orthogonal array and the levels for the minimal simulation times and the best of the combination of parameters. Applying the result into the DEFORM-3D simulation to explore the feasibility to cut down the times and duration for the simulation period. Simulation results show that upper punch dies, location of the main areas of high stress break location consistent with the experimental die. Corrects upper punch break position Radius and the angle, the maximum stress value was revised by the 1720MPa to 1480Mpa, to solve the break of the upper punch position. The experiment results are available for the precision cold forging R&D and production management in the forging industry.
