Abstract
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.
