Abstract
A fluid jet cutter utilizing a multitude of heads and flexible pressurized feed system is disclosed. The cutter utilizes a carriage which has mounted on it a plurality of fluid jet cutting heads which are maintained in registration with jet catchers operably disposed beneath the carriage. The cutters and jet catchers are movable either as a unit in synchronization with each other or moved separately to be spaced apart from a center head. Cutting in the Y-direction is effectuated by means of head movement along the carriage. Cutting action in the X-direction can be effectuated either by movement of the carriage or, alternatively, by movement of the cutting table bed. A tower disposed outside the cutting area is used to provide high pressure fluid to the cutting heads. The tower, with its flexible coupling, reduces the dynamic loads on the positioning system for the cutter heads, thereby allowing increased performance. Coverage of the full cutting area is effectuated by use of an overhead boom configuration coupled with a helical coil capable of extending and bending during motion of the carriage.
