3. Cutter axis is set radial with respect to gear blank.
Cutter is a Shank type cutter which is mounted directly on spindle of Vertical Milling Machine.
Cutter axis is set radial with respect to gear blank.
The blank is then indexed to the next tooth position as in case of milling with disc type cutters . It is suitable for producing pinions of large pitch.

4. The disc cutter shape confirms the gear tooth shape
The disc cutter shape confirms the gear tooth shape. Each gear needs separate cutter. However, with 8 to 10 std. cutters, gears from 121 to 120 teeth can be cut with fair accuracy. Tooth is cut one by one by plunging the rotating cutter in to the blank.
