    Gear-cutting machines. Three basic cutting methods are used for machining gears (1) form cutting (2) template cutting and (3) generating. The form-cutting method uses a cutting tool that has the same form as the space between two adjacent teeth on a gear. This method is used for cutting gear teeth on a milling machine. The template-cutting
