This one is mounted on tool slider, which can execute in the same time the feed and rotation movement, due to universal joint and involute spline
One part required 27 involute splines (30 index), 11 diametral pitch, 30 deg pressure angle, 2.
The process is rapidly becoming a viable alternative to gear hobbing in producing external spur gears, involute splines, and other special and interrupted tooth configurations because of the speed and tooth-finish that is possible.
Because the external helical teeth and straight involute splines
are molded in, the secondary operations required are deburring and minor machining.
That dictated the use of involute splines
to optimize the tiny surfaces of the gear and spline teeth.

Polygon shaft-to-hub connections can transmit twice the torque of involute splines
in the same shaft diameter, due to the elimination of stress concentration risers.
