On the profile change of conical skiving tools after re-sharpening

Gear skiving is a productive process for manufacturing internal gears that has been spreading among companies in recent years. In gear skiving, conical shaped tools are used to avoid interference during machining. However, due to the conical shape, both the tool tip diameter and the tool profile change after re-sharpening, leading to a change in cutting performances during the tool service life. This paper aims at investigating the impact of the profile change on the process through simulations and experiments. Sensitive tools to profile change are identified and a strategy to reduce the difference in cutting performances is proposed.
