Short answer: Gears are made by cutting teeth into a blank — hobbing for spur and helical gears, shaping for internal teeth, broaching for splines — then hardened and finish-ground for quiet, accurate running. The method is chosen by tooth geometry, volume and the hardness the gear must reach in service, with tight control of pitch, profile and runout.
