| Abstract: | A new two-stage precision forging process for spur gears with inside relief was developed,and 3D rigid-plastic FEM was used to simulate the forging process with different parameters of the die in order to achieve the optimum parameters of the die. According to the simulation and experiment results, the flow ability of the material is improved and a lower forging load is obtained in the new process which is effective for the forging process of spur gears. |
