ABSTRACT:
The boss of a steering wheel is serrated by setting the steering wheel on a serrating broaching machine, inserting a serrating broach into a through hole defined in the boss of the steering wheel, and then pulling the serrating broach with a broach chuck gripping the serrating broach to cut serrations on an inner surface of the through hole in the boss. The steering wheel is positioned nonrotatably in a prescribed angular orientation on the broaching machine while placing the boss on a holder of the broaching machine. Then, the serrating broach is inserted through the through hole in the boss into the holder of the broaching machine while holding the serrating broach in a prescribed angular orientation around the axis thereof with respect to the broach chuck. Finally, the serrating broach is pulled from the boss with the broach chuck gripping the serrating broach to cut serrations on the inner surface of the boss.
