Explain Gear Milling

Milling is a form-cutting process limited to making single gears for prototype or very small batches of gears as it is a very slow and uneconomical method of production.

A in volute form-milling cutter, which has the profile of the space between the gears, is used to remove the material between the teeth from the gear blank on a horizontal milling machine. The depth of cut into the gear blank depends on the cutter strength, set-up rigidity and mach inability of the gear blank material.
