Experimental and Numerical Study on Enclosed Die Forging of a Precision Bevel Gear

In this paper, we present a systematical procedure to develop a precision enclosed die forging process for a bevel gear of a passengers' car. The detailed procedure involves bear gear CAD modeling, process design and CAE simulation, CAM and die making, material preparation, and prototype manufacturing using both the technologies and machines accumulated and equipped in the technology innovation center(TIC) of Gyeongsang National University. It is demonstrated that the presented approach guarantees bevel gears with the second KS grade quality, which can be used for the differential gear of the passengers' car.
