Abstract
A method for measuring wall thickness of an annular material during a manufacturing process includes the steps of hot die forming an annular material, employing an ultrasonic gauge about the formed annular material while in a hot state and which is operably equipped to produce an output signal indicative of concentricity thereof, and employing a computer based device to calibrate the ultrasonic gauge using a calculated finished cold formed wall thickness for the annular material. The method further employs a laser gauge to provide an output to the computer indicative of the outer diameter size of the formed annular material when cooled, wherein the computer uses the output in determining the calibration. A system is also provided.
