With the development of production, the smoothness of gear operation has received attention. Gears are mechanical parts with teeth that can mesh with each other. They are extremely widely used in mechanical transmission and the entire mechanical field.
[0003] Gear shaping is the process of machining the tooth surfaces of internal and external gears or racks by using a gear shaping cutter according to the developing method or forming method. Gear shaping is the process of machining the tooth surfaces of internal and external gears or racks by using a gear shaping cutter according to the developing method or forming method. Gear shaping can process both straight and helical gears; gear hobbing can also process straight and helical gears, but gear hobbing is more efficient. The gear shaping cutter is equivalent to a pair of cylindrical gears with parallel axes meshing. The gear shaping cutter is essentially a gear with a front and rear angle and a cutting edge.
