ABSTRACT:
Tooth flanks of a gear are produced with a cutter head rotating about a cutter head axis and equipped with cutters having internal or inner cutting edges and external or outer cutting edges. In order to obtain a further increase in the gear cutting capacity or output, while avoiding the therewith usually associated tooth flank errors, the cutter head axis is pivoted out of a normal within or into a plane, as the case may be. At the cutter head the external cutting edges are arranged at a first circle, the internal cutting edges at a second circle and such respective cutting edges are arranged in offset relationship from a uniform angle division or pitch through a predetermined respective angle. The external cutting edges and the internal cutting edges form with a normal to a tangential plane a respective predetermined angle.
