A cutter head () having a lock spring () utilized with an adjustment screw () for preventing the adjustment screw from loosening during machining. Once positioned by turning the adjustment screw, a cutting blade () will not change position in a mounting slot () due to a loosening adjustment screw.

Lock spring and cutting tool having a lock spring

Generating cutting processes for producing bevel gears and employing a single rotary disc cutter () wherein a portion of the generating cutting process effectively includes a reduction () of the workpiece roll angle () during generating thereby reducing or eliminating cutting action on the clearance side () of the rotary disc cutter.

Slide rolling process for the generation of bevel gears

Method and apparatus wherein the front machining of a gear blank () are carried out on a CNC bevel gear generating machine () utilizing the motions available in such machines with minimal modifications to the existing machine tool.

Method for manufacturing bevel gears

A method of forming a relief at the toe end of the teeth on a bevel gear is disclosed. The width of the blades that cut the longitudinally extending convex or concave profiles of the flanks of the teeth is increased to a dimension greater than the width of the tooth slot at the toe end whereby additional stock is removed from the toe end of the flank opposite the flank being cut by the blades. The relief is formed at the toe end of each tooth with the relief being on the same flank profile for all teeth. Lapping interference is eliminated. A separate chamfering operation is not required.
