A cutting blade for face milling wherein the cutting blade is constructed to cut a predetermined final dimension of a tooth slot along a portion of the cutting end (i.e. the primary cutting edge portion) of the blade and to cut the remainder of the tooth slot at an amount less that the predetermined final dimension of the tooth slot along the remaining portion (i.e. the secondary cutting edge portion) of the cutting end. The construction of the inventive cutting blade provides sharing of the cutting load amongst the blade cutting edges and also provides sufficient clearance in the tooth slot whereby the cutting blade can be repositioned to allow truing of the cutter, particularly with respect to the primary portion.

Full point width cutting blades

A method and tool arrangement for producing straight bevel gears and the like on a multi-axis computer controlled machine wherein a single tool is utilized in the machining process.

Manufacturing straight 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.
