Large-scale engineering software UG was regarded as geometric modeling tool to create the performing die.The effects of shape and size on forming results were analyzed aimed at different performed workpieces; the problem of necking down was discussed also. According to the results of 3D FEM numerical simulation, it can get the best shape and size of perform ingot.Using the finite element technique software Deform,3D thermo-mechanical coupled numerical simulation of the blade forming process was carried out. The research indicates that with increasing friction coefficient, material flow is poor, plastic deformation resistance and friction heat increase, the highest temperature rises. So, the selection of smaller coefficient of friction with the value of 0.1 is more reasonable.By comparing simulation result with the application of the results, the simulation process can be further verified to be reasonableness and practicability.
