Generic Gear Shape
Gears used in the design of various machines and mechanisms are somehow machined on machine tools. Nowadays, machine tools, especially numerical control machines, are capable of performing any desired motion of the cutting tool in relation to a workpiece. This makes it possible to machine a gear that has any desired tooth ank geometry. Using any desired motion of the cutting tool with respect to the work-gear is not a common practice in machining gears, especially machining gears in high-volume production industries.
