Abstract

There is disclosed an improved method for manufacturing wheels in a production line by: hot-shaping metal into wheel-shaped articles which are larger in some areas than the wheels to be formed and which have a plurality of complexly-curved inner and outer surfaces; cooling the wheel-shaped articles and removing excess metal from some areas of the wheel-shaped articles. The improvement comprises: inspecting at least some of the wheel-shaped articles at a plurality of points along a transverse plane through the inner and outer surfaces of each article being inspected and at a plurality of transverse plane locations about the perimeter of each such article with a contactless gauging system recently after the articles have been hot-shaped to determine whether the articles are within dimensional requirements to form a wheel therefrom. The improvement further comprises taking corrective action to the hot-shaping operation to minimize the number of unacceptable wheel-shaped articles that are being formed after finding an article which is not within dimensional requirements.
