Abstract
Method and apparatus for lapping gears which includes an active torque system to substantially improve the lapping process with respect to run-out and other longer-term motion transmission errors without compromising tooth-to-tooth performance. Motion transmission error measurements provide the basis for calculating a corrective active torque component which is combined with conventional process torque to reduce or eliminate part run-out.
