Research on the cutting mechanism of cylindrical gear power skiving

Latest research clearly demonstrates the excellent capability of the gear power skiving technology. For further improvement of the skiving process and enhancement of the process reliability, the fundamental research on the cutting mechanism of cylindrical gear power skiving was conducted. First, the kinematic model of power skiving and mathematical of tapered skiving cutter were established according to the engagement principle of crossed helical gears. Then, the simulation process and chip deformation mechanism were developed. Based on the proposed modeling, we investigated the cutting mechanism, including the cutter top rake angle related to the cut strategy, skiving accuracy with respect to the gear number, and tooth ratio. The results support the skiving cutter design and process optimization and are an important basis for the implementation of the advanced gear process.
