Spur gear generation by shaper cutters

This paper proposes the computerized tooth profile generation of spur gears cut with shaper cutters. A complete geometrical mathematical model of a spur shaper cutter is proposed, including the protuberance, the involute region and semi-topping. The profiles of standard or non-standard spur gears cut with the shaper cutter are obtained based on the theory of gearing. In addition, the effects of the cutter parameters on the generated tooth profile are investigated and illustrated with computer simulation, while the appropriate shaper cutter parameters corresponding to the required gear profile, are also determined using an optimization method.
