ABSTRACT:
An automated workpiece rotation is accomplished by clamping the workpiece, to the lower turret of a turret punch press in the press carriage grippers and rotating the turret 180.degree. to reorient an oversized workpiece in order to enable completion of a punching program on the workpiece. The turret is positively located in each rotated position, and the degree of tilt of the rotated sheet in the press carriage grippers is determined by edge detectors.
