FIELD: machine engineering, namely gear cutting tools.
SUBSTANCE: milling cutter includes helical cuttings grooves. In order to enhance strength, inclination angle of front face of grooves (according to mean designed cylinder) exceeds lead angle of turns of milling cutter. Value of angle of tooth apex of milling cutter is optimal for concrete conditions of gear milling.
EFFECT: improved strength of milling cutter.
