Laser cutting has professional computer-aided numerical control programming software, and the preparation of part processing programs is generally completed on an offline computer. Some simple processing programs can also be directly completed in the editing interface of the CNC system, but it takes a long time and cannot program and sort complex components.

It is generally not recommended to program CNC programs on a CNC system, as it takes up a large amount of machine tool usage time and is inefficient. After placing the sheet on the machine tool workbench, it is important to determine the coordinate system of the workpiece processed by the machine tool, which should be completely consistent with the coordinate system set in CNC programming.
