To improve strength and vibration and noise, it is important to remove the burrs and pits generated at the edges of gear teeth during the gear cutting process. However, as the tooth groove of the small gears in compact geared motors is small, removal of such burrs and pits is difficult due to space constraints. To address this, a gear-shaped tool composed of glass fiber-reinforced plastic (GFRP) has previously been proposed and the effectiveness of the removal process using it has been confirmed. However, in some cases, the method does leave burrs and pits in the position on the pitch circle. Herein, to address this issue, an improved method is proposed which introduces oscillation to the GFRP gear-shaped tool. A theoretical analysis of the sliding velocity at the tool/work-piece interface is also presented. The apparatus for the process was constructed and used to validate the proposed method experimentally.
