Abstract：

During the forging process, friction could not only increase the die load and deformation temperature, but also influence the strain distribution and material flow. Based on the study on forging process by FEM, this paper put forward a method to optimize the material flow and flow velocity by changing the local friction of dies, and consequently avoids the forming defects of forging pieces and make sure the material can fill the dies. This method is used in the forming process of hub and crank, and be tested effectiveness.
