A multistage warm/hot forming is simulated for the cross grove outer race of constant velocity joint, using athermo-mechanical coupled rigid viscoplastic finite element method, and specially some problem for process development and die design are analyzed. A forming test shows that computed results have good agreement with experimentalresults. Above obtained results can be applied to development of multistage warm/hot forming process and die designfor outer race.
