ABSTRACT:
Apparatus for milling a gear for a double enveloping worm gear drive. A rotating milling cutter is advanced toward a workpiece spindle to mill a flank of a gear tooth by tilting the milling cutter supporting frame about an axis that passes through the axis of rotation of the workpiece spindle to form a predetermined change in the helix angle from the top to the root of the tooth. The initial tilt setting of the cutter is adjusted to suit the root helix angle.
