Precision Electric Discharge Machining of a Cold Forging Die for Helical Gear Manufacturing

헬리컬기어 냉간단조 금형의 정밀방전가공

In this paper, the precision electric discharge machining technology, the powder electric discharge machining technology, is applied to making a cold forging die for making the helical type of clutch gear. Various working conditions are investigated with emphasis on reduction of the electrode wear and enhancement of the surface roughness. Through the research work, the key technology of making the helical gear forging dies is achieved.
