  • Roughing gear shaper cutter
    Patent number: 4139327
    Abstract: A gear shaper cutter for generating rough shapes has an undulating cutting edge profile to leave alternating heavy and light sections of material to be removed from the rough shape in a finishing operation. Chips are, as a result, more easily broken during the subsequent finishing operation to provide better heat dissipation and longer finishing tool life.
