Abstract

Computer numerical control (CNC) machines have dramatically changed manufacturing processes including plasma based cutting. Typically, plasma based cutting executes a single continuous process. However, gratings cut from a grating sheet require a number of discrete cuts be made within a grating sheet to cut each element within the grating sheet to isolate the element required from the grating. Accordingly, embodiments of the invention provide enterprises and facilities employing CNC cutting systems with a means to overcome the limitations of CNC cutting systems when cutting such elements.
