Current processing methods of face gear are mainly limited to gear shaping, gear hobbing, and other processes. In order to achieve high-precision and high-efficiency machining of face gear, this paper proposed the cutting technology and tool design of face gear skiving. Solving the tooth surface of the skiving cutter according to the meshing principle, and fitted by NURBS surface. Intersecting the rake and conjugate face to obtain cutting edge data, and import it into the CAD software to build the skiving cutter model, the tooth surface enveloped by the cutting edge of the skiving tool is solved according to the envelope principle. This paper proposed the machining principle and tool design method of face gear skiving and analyzed the influence of tool tooth profile error and installation error on the face gear tooth surface deviation, which provides a reference for improving the machining accuracy and efficiency of face gears and further improving the gear skiving process.
