| Helical gears adapted to mesh while rotated about parallel axes, are finished by meshing engagement with a shaving cutter gear rotated about an axis at a fixed cutting angle to the rotational axis of the helical gear being finished. A contact ratio close to but never less than one is established during meshing engagement between the helical gear being finished and the finishing gear by designing the helical gear teeth profiles within the limits of a contact ratio range applicable to meshing helical gears rotating about parallel axes.

| A tool for the precision working of gears by chip removal therefrom such as in gear shaving and of the type wherein the flanks of the tool teeth comprise a plurality of alternate grooves and lands having a novel cutting edge construction between the surfaces of said lands and the walls of the adjacent grooves and between the tip surfaces of the tool teeth and the land adjacent thereto. Particularly said walls and the tip surfaces adjacent thereto are provided with cutting edges for plunge shaving wherein with a given relief angle the rake angle may be positive, negative or zero.
