In this paper, a multistep warm/hot forming is simulated for cross grove outer race of constant velocity joint , using a thermo mechanically coupled rigid visco plastic finite element method, and specially some problem for process development and die design is analyzed. Obtained results can be applied to development of multistep warm/hot forming process and die design for outer race.
