Abstract
A metal cutting apparatus which comprises a longitudinally moveable gantry and a transversely moveable carriage which is mounted on the gantry. The carriage in turn mounts a laser cutting head and a plasma arc cutting head mounted in a parallel, side-by-side arrangement. The apparatus may thus be programmed to operate either the laser cutting head or the plasma arc cutting head as the gantry and carriage move in a predetermined path above the underlying workpiece. The laser generator is mounted in the gantry so that the beam is transported to the laser head with minimal bends and turns. The apparatus may also include a second carriage, which mounts a second laser cutting head and second plasma arc cutting head, so as to permit simultaneous cutting along two cut lines.
