Abstract

On CNC shaving machine, the tooth flank of work gear can be crowned longitudinally by varying the plunge motion of shaving cutter. However, which will induce a bias error on tooth flank of the shaved work gear. In this paper, therefore, we propose a new CNC shaving method by modifying work gear rotation angle and without varying the plunge motion of shaving cutter during the gear shaving process that can be reduced the bias error of the tooth flank on shaved work gear. A numeral example is presented to illustrate and verified the merits of the proposed CNC gear shaving method in longitudinal crowning to obtain the tooth flank of work gear surface without bias error.
