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.
Claims10
A system for forming a feature on an inner surface of a gear, the system comprising:
- a cutting device having a cutting edge for forming the feature in the inner surface of the gear;
- a sensor for detecting a feature on an outer surface of the gear;
- and
- a controller in communication with the sensor and the cutting device, the controller having a first control logic for determining the angular orientation about a center axis of the gear of the feature on the outer surface of the gear with respect to the cutting edge, a second control logic for determining an amount of rotation required to position the cutting edge and the feature on the outer surface of the gear at a desired orientation, a third control logic for rotating at least one of the cutting edge and the gear the amount required to orient the cutting edge and the gear to the desired orientation, and a fourth control logic to move the cutting edge through the gear such that the cutting edge forms at least one feature into the inner surface of the gear, wherein the at least one feature on the inner surface is positioned relative to the feature on the outer surface at the desired orientation.
