Abstract
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.
