In order to solve the flank concave problem of the rotary gear shaving cutter, a new worm type shaving cutter has been manufactured, which will be used on a gear hobbing achieving freedom shaving. And its tooth precision can reach 6-7 level. The main contents includes the worm normal section curve equation of the worm type shaving cutter involutes, the optimization of tooth fitting error and the linear fitting of the tooth curve of the normal section by the MATLAB genetic algorithm toolbox. According to GB/T6084-2001 hob series standard, the results showed that the error theory is less than 1/6 of the AA level.
In order to solve the problem of tooth concave error appeared in the shaving course of non-modification disk-shaped shaving cutter, the worm type shaving cutter of open groove is studied. Firstly, the basic structure of the shaving cutter and the manufacturing process will be introduced in detail. The angle of front cutting edge is -30 ° or 30 °, and then the coincidence degree is approximately equal to 2, when the tool cut the gear in the direction of the oblique angle. Secondly, the tooth profile precision will be able to be achieved though circular grinding method based on both sides of the worm. Finally, the free shaving principle is discussed by analyzing the shaving movement, the drive speed and the cutting speed. According to the shaving gear experiment, the results show that the tooth precisions reach to the 6 grades.
