SYSTEM AND METHOD FOR NC PLASMA CUTTING OF METAL FABRIC

摘要

Systems and methods NC plasma cut a metal fabric based upon a two-dimensional cutting path. An NC cutting machine is controlled to make a first pass along the cutting path with the laser height measuring device to collect height data from the metal fabric positioned on a bed of the NC cutting machine. Positions for starting and stopping a plasma arc of a cutting torch of the NC cutting machine are determined based upon the height data. An enhanced NC program is generated based upon the cutting path, the height data, and the positions for starting and stopping the plasma arc, to control the NC cutting machine to cut metal of the metal fabric along the cutting path.

主权项

1. A Numerical Control (NC) cutting machine for plasma cutting a metal fabric, comprising:
a computer having a memory and a processor; a laser height measuring device; an NC program stored within the memory defining a cutting path; and a fabric enabling software having machine readable instructions stored within the memory that when executed by the processor are capable of:
controlling the NC cutting machine to make a first pass along the cutting path with the laser height measuring device to collect height data of the metal fabric positioned on a bed of the NC cutting machine;determining positions for starting and stopping a plasma arc of a cutting torch of the NC cutting machine based upon the height data; andgenerating an enhanced NC program based upon the NC program, the height data, and the starting and stopping positions to control the NC cutting machine to move the torch at an optimal cutting height over the metal fabric in a second pass along the cutting path to cut metal of the metal fabric.
