Research on Reduction of Cutting Force in Gear Power Skiving by Considering the Radial Infeed Strategy

The high cutting load in gear power skiving is a severe problem. In this research, the cutting force is reduced by employing different radial infeed strategies while maintaining the cutting efficiency. Setover is applied to realize an additional motion of the cutter for varying local cutting conditions. The numerical analysis on uncut chip geometry was carried out to investigate influences of setover, followed by the experimental verification. As a result, setover imposed great influences on the cutting process including the cutting chip, cutting force, etc. In the cutting force measurement experiment, the proposed feed strategy achieved a force reduction up to 49% in most compared with the conventional radial infeed strategy.
