Abstract
A method of manufacturing a part with a tooth profile by cold forging includes an initial step of forming a initial tooth profile and a finishing step of forming a completed tooth profile by sizing. Between the initial step and the finishing step, is an intermediate step tooth thickness of the initial tooth profile is either maintained or reduced by 10% or less from the tooth thickness of the initial tooth profile. In the intermediate step an addendum part is expanded beyond the initial tooth profile by cold forging.
