Abstract: A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a stop member movable along one of the X and Y axes and a clamping element for clamping the workpiece in the stop member for movement therewith. The clamping element is movable independently of its associated stop member as well as therewith, and one stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. In one embodiment, the clamping element is a claw or clamp in a fixed position on the stop member and which is automatically actuable to clamp the workpiece or to release the workpiece for guided movement thereby. In another, the clamp is slidably supported in the stop member for movement relative to a base element to provide clamped guiding movement for the workpiece and also can be locked in a position to fix the workpiece therefor.
