Abstract
An apparatus for inhibiting movement of a workpiece comprises a bed, a pair of opposed vise jaws associated with and extending from the bed, each of the jaws having a gripping surface and at least one of the jaws being movable for gripping and releasing the workpiece positioned between the jaws, and a movable projection member rotatably disposed in a recess in the gripping surface of one of the jaws, where the projection member is extendable outwardly in a direction generally transverse to the gripping surface between the pair of jaws for being positioned above the workpiece when the workpiece is positioned between the jaws without exerting a substantial force on the workpiece to inhibit fly-away movement of the workpiece. In addition, a method for inhibiting fly-away movement of a workpiece using the apparatus of the present invention comprises placing the workpiece on the bed between the jaws, moving the movable jaw to a position to grip the workpiece between the gripping surfaces of the jaws and positioning the projection member to a position above the workpiece without exerting a substantial force on the workpiece.
