  • Method and system to manufacture oriented internal and external gear teeth
    Patent number: 8251620
    Abstract: A system and method for forming a feature on an inner surface of a gear includes a sensor for sensing the position of a feature on the gear, a cutting station having a cutting tool for forming the feature on the inner surface of the gear, and a controller. The controller is operable to determine an amount of rotation necessary to rotate either the gear or the cutting tool such that the feature on the inner surface of the gear is formed at a desired orientation relative to the feature on the outer surface of the gear.
