Effect of Preshaved Form and Cutter Performance in Plunge Cut Shaving

Abstract

The present paper describes a new method of simulation program for plunge cut gear shaving. The developed program estimates the shaved form as follows. First is generation of tooth flanks of the work gear and the shaving cutter from gear data. Second is estimation of initial mismatches between tooth flanks of the work gear and the shaving cutter as depth of cut. Third is calculation of stock removal of work tooth flanks from the depth of cut. The program can simulate in consideration of an effect of preshaved form and the cutter tooth form modification. In addition, the program can simulate in consideration of an effect of cutter performance. The cutter performance has been evaluated from slide velocity between the tooth flanks of the work gear and the shaving cutter. The effect of accuracy of preshaved form and cutter performance on the shaved form was investigated using the developed program. As a result, requirement of accuracy of preshaved form and cutter performance are proposed.
