Abstract
A programmable bed is provided for machine tools and the like, such as routers, boring tools, and other powered cutters and shapers. The programmable bed has a platen shaped to support differently sized workpieces thereon, and includes a plurality of retractable stops slidably mounted in the platen. The stops are selectively and individually shifted vertically between extended and retracted positions in response to the identification of a particular workpiece, so as to automatically locate or index the same on the platen at a preselected position relative to the machine tool. A plurality of pop-up suction chucks are also slidably mounted in the platen, and are selectively communicated with a source of vacuum. The suction chucks are reciprocated vertically between a retracted disengaged position, and an extended engaged position abutting an adjacent surface of the workpiece, so as to securely retain the workpiece in its preselected position during the machining operation.
