Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets using a hobbing machine, a specialized milling machine.The teeth or splines of the gear are progressively cut into the material (such as a flat, cylindrical piece of metal or thermoset plastic) by a series of cuts made by a cutting tool called a hob.
These were used by large mills for cutting metal. Their Gear Hobbing Machine came out in two sizes in 1910 and could precisely cut teeth in gears. In 1919, the company purchased the rights to the Warp Drawing Machine from the American Warp Drawing Machine Company. This machine eased the transition of switching warping patterns.
