According to the shape character of half axle bevel gear forging a process based on closed-die forging scheme was proposed. Based on a series of simulation the influence of initial forging temperature on forming force, the influence of web thickness and web position on stress, damage factor and forming force were analyzed. According to numerical analysis the web dimensions and forging temperature which ensure a minimum stress, a minimum damage factor and a proper forming load were achieved. The forming result was simulated and evaluated, and the forming load was controlled under 760ton. At last the research project got good test verifying.
