Gear hob is a continuous generating process which can be compared to kinematic conditions of worm and worm gear. The workpiece is represented by the worm gear whereas the hob tool is designed like the worm (Fig.1, top left). By a continu - ous rotation ω 0 of the tool, the cutting movement is realized. An axial feed a

FIG.FORM MILLING PROCESS 5) Hob In hob the hob tool is used. Hob tool also known as hob. Hob is rotated at suitable speed. Then it is feed into rotating gear blank. It is feeded up to required thickness. As compared to milling process it is fast hence it is suitable for mass production. FIG.HOB PROCESS 6) Shaping

1986/1/1 · Gear shaving is a free-cutting gear finishing operation which removes small amounts of metal from the working surfaces of the gear teeth. Its purpose is to correct errors in index, helical angle, tooth profile and eccentricity. The process can also improve tooth surface finish and eliminate, by crowned tooth forms, the danger of tooth end load concentrations in service.
