Abstract
A method of verifying the roundness of a clutch hub includes placing the clutch hub adjacent a non-contact measuring device. The method includes rotating one of the clutch hub and non-contact measuring device about a central axis that is stationary relative to the non-contact measuring device. Distance measurements are measured between the non-contact measuring device and a surface of the clutch hub at discrete points along splines and slopes between the splines of the clutch hub as the clutch hub is rotated about the central axis. The method includes identifying some of the distance measurements as spline measurements associated with splines of the clutch hub. The roundness of the clutch hub is calculated based on the spline measurements.
