Abstract
A process for forming a finished spiral bevel gear includes forging a blank to form a forging having near net-shaped spiral bevel teeth, machining the forging, coining the forging to form a coined spiral bevel gear with net-shaped spiral bevel gear teeth; heat treating the coined spiral bevel and finishing the heat treated, coined spiral bevel gear without machining the net-shaped spiral bevel gear teeth in a machining operation that forms chips.
