Gear manufacturing - Sandvik Coromant

Hobbing is a gear manufacturing process in which gear teeth are generated through a series of cuts with a helical cutting tool. The hob and gear blank are rotated continuously until all teeth are cut. Hobbing is only possible for external gears. Gear hobbing advantages. Reduced total cost per gear wheel compared to HSS tools; High cutting speeds

Hobbing - Wikipedia

Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine.The teeth or splines of the gear are progressively cut into the material (a flat, cylindrical piece of metal) by a series of cuts made by a cutting tool called a hob.Compared to other gear forming processes it is relatively

Gear gashing is a gear machining process, very much like gear milling, utilizing the principle of cutting one or more tooth (or tooth space) at a time. The term "GASHING" today applies to the roughing, or roughing and finishing, of coarse diametral pitch gears and sprockets. Manufacturing these large coarse gears by conventional methods of rough and finish hobbing can lead to

If you desire a gear ratio of 2:1 then your gear wheel will have tw as many teeth as your pinion. However, your gear with more teeth would need need to be tw the size in order to have the same sized teeth.

Milling (machining) - Wikipedia

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
