A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth, which mesh with another toothed part to transmit torque. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source.

There are many methods for manufacturing gears, including:

  • Metal removal processes (hobbing, shaping, milling, shaving, grinding, honing, and lapping)
  • Various casting processes for both production of gear blanks and near-net shape gears.
  • Stamping and fine blanking.
  • Cold drawing and extrusion.
 
To manufacture a gear on a milling machine the following configurations is required:
