Abstract

A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a first stop member movable along one of the X and Y axes and a clamping element a second stop member for clamping the workpiece against the first stop member for movement therewith. The second stop member element is movable independently of its associated first stop member as well as therewith, and each stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. The machine tool also includes a computer system control for operating the motors which drive the guide assemblies.
