The helical gear is one of the main parts of the mechanical transmission system. Its tooth surface accuracy and meshing quality are the keys to ensuring the comprehensive performance of mechanical products, such as efficiency, noise, transmission accuracy, and service life. The helical gear tooth surface structure is complex, and its processing accuracy and meshing quality control have always been complex problems in gear manufacturing technology. Due to the geometric characteristics, meshing process, and gear cutting machine structure of the helical gear, the adjustment of the gating is the most complicated. At the same time, the processing tools, the parameter setting of the processing tool, loading deformation, and assembly errors will cause its meshing, bearing, and vibration. The change in performance makes the quality control of helical gears rugged in design and manufacture. And its particular purpose and excellent meshing performance have strict requirements on the geometric accuracy and meshing quality of the tooth surface. Therefore, improving the machining accuracy and weaving quality of the tooth surface of the helical gear has been the object of extensive attention and research by experts and scholars in various countries. It has become the equipment manufacturing industry's critical technology and ultimate goal.
