Abstract：

For the problem that the cam components are difficult to be processed by plastic forming due to the complex outer contour,

based on its geometrical structure characteristics, a two-step

multiple degrees of freedom (MDOF) rotary forging process was proposed to manufacture the cam components, and the

pre-forming and final forming molds of MDOF rotary forging for cam components were designed. Then, their finite element models were established, and the evolution laws of metal flow, effective strain and forming load were revealed by the finite dement simulation. Furthermore, the pre-forming and final forming process experiments for MDOF rotary forging of cam components were carried out. The results show that the finite element simulation results are consistent with the experimental results, which indicates that it is feasible to manufacture cam components by two-step MODF rotary forging process.
