It was proposed that a production method in which a spur gear was made from the drawn cup by plastic working. This forming method consists of four processes, namely drawing, re-striking, ironing and compressing process. However, the forming of steel gears isn't suitable for the actual production because the forming pressure in the compressing process is too high. And, filling ratio is not also enough. So, It is examined to reduce forming pressure and to improve filling ratio by two types of the divided flow forging method. It is found that divided flow methods be able to improve of filling ratio and to reduce of forming pressure. A deformation mechanism by the FEM simulation is very similar to the experimental result, and it can estimate state of filling up in the tooth top and forming pressure.
