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 … Se mer Hobbing uses a hobbing machine with two skew spindles. One spindle is mounted with a blank workpiece and the other holds the hob.
