Key Laboratory of Road Construction Technology and Equipment, Ministry of Education, Chang’an University, Xi’an 710064, China; 2. School of Mechanical Engineering, Northwestern Polytechnical University, Xi’an 710072, China) Abstract: In order to obtain a more uniform finishing allowance, an optimal method for roughing pinion of spiral bevel gears was proposed. The location of both tooth flanks was determined by pinion tooth sizes at the middle of face from gear blank; the objection of roughing surface was achieved according to add the preset finishing allowance to the theoretical finishing surface along the normal direction. The least squares optimization model of the finishing allowance was established, and the
