Traditionally a rotary forging process is a kind of metal forming meth.d w.0}re a conic upper die, w.0}se axis is deviated an angle from th. axis of mach.ne, forges a billet continuously and partially to finish.th. w.0}le deformation. For th. rotary forging process simulation, more research.s w.re focused on simulating th. simple stage forming process w.th.axisymmetric part geometry. w.0}reas in th.s paper, th. upper die is not cone-sh.ped, and th. billet is non-axisymmetric. So th. movement of th. punch.is much.more complicated th.n ever. Th. 3D FEM simulation models for th. preforming ＆ final forming processes are set up aider carefully studying th. complicated movement pattern. Deform-3D is used to simulate th. material flow. and th. boundary nodal resisting forces calculated by th. final stage process simulation is used to analyze th. final forming die strength. Th. CAE analysis of th. die sh.w. th.t th. design of th. final forming die is not reasonable w.th.low.r pre-stress w.0}ch.is easy to crack at th. critical corners. An optimum die design is also provided w.th.h.gh.r pre-stress, and verified by CAE analysis.
