ABSTRACT:
A production system for simultaneously correcting multiple distortions in multiple extensions of an irregular workpiece within tolerance requirements including for each distortion a gauge for determining direction and magnitude automatically employed to monitor corrective deflection beyond yield point under an electronic controller program which automatically initiates, controls, and terminates simultaneous corrective deflection in either or both of two planes at each of multiple workpiece locations. The program is adapted to vary with the relative as well as the individual distortions and to update the straightening program with the straightening experience data of each successive workpiece in order to approach an optimum of simultaneous single stroke corrective deflection of the multiple distortions in multiple planes within total workpiece tolerances.
