Abstract：

Considered to metal flow direction, two near net shape process programs for ratchet and involute gear were proposed. Deform-3D was used for these two programs to analyze the metal flow characteristics of the forming process. The results show that the involute tooth's radial flow difficulties will lead to other parts excessive deformation and folding in radial expansion forming. The vertical restraints flow forming method realizes the near net shape of the ratchet and involute gear due to the smooth materials flow and less load demand.
