ABSTRACT:
A machine for cutting the border of a workpiece using one or more water jet cutting tools separately carried by one or more monorail track mounted carriage assemblies is disclosed. The machine can also include an aperture forming apparatus for forming circular openings and/or elongated slots in the workpiece prior to/or simultaneously with the border trimming operation, all while the workpiece occupies a single work station in the machine. In one embodiment, the aperture forming apparatus features a cutting tool mounted on an elongate arm affixed to and extending from a plate which is fixedly oriented in a horizontal plane. While so oriented, a motor and gear assembly causes the plate to wobble in a circular pattern in the plane to, in turn, cause the tool to make a circular cut in the workpiece. In another embodiment of the apparatus, a motor rotates a cam carried on a free end of a stationary arm, the cam containing an eccentrically mounted cutting tool.
