Abstract
This invention is directed to a method of using a two spindle Hurth-Module multi-spindle (or similar) cutting machine to accomplish face hobbing of hypoid and spiral bevel gear sets. A first cutter mounted on a first spindle would rough cut the gears and a second cutter mounted on a second spindle would finish the gears with both cutters using a face hobbing process. According to this process, multiple cutters are used for a single gear, but on a single machine, thereby reducing cutter wear, increasing cutter life, and raising production output of the multi-spindle machine by utilizing both spindles. In one embodiment, a fine pitch cutter is used to create the initial rough-cut of the gear, and a second coarse pitch cutter is used to create the finish cut of the gear.
