Abstract：

The manufacturing method of shaft\|disc type components used widely in industry are ordinarily to machine the shafts and discs separately, and then assemble them. Such process is often time\|consuming. The new process, i.e. thermal differential dieless can realize near net forming of shaft\|disc type components,thus by which the difficulties existing in traditional manufacturing process may be solved.In this paper,the thermal differential dieless forging of local\|ring\|heated cylindrical billet is simulated by coupled thermal\|viscoplastic FEM,and the feasibility of preforming shaft\|disc type components by this new process is theoretically validated.
