Abstract: The forging process of blade with a tenon is simulated and analyzed by using a 3-D FEM code developed in order to obtain forming laws in the precision forging process of blade. Physical modeling validates the results of numerical simulation using plasticine as modeling material. A good agreement of numerical simulation results and physical modeling results shows that the results of the numerical simulation are reliable in the forging process of blade with a tenon. This study is important to optimum design of the billet in the precision forging process of blade.
