CNC program example to cut Quincunx on a CNC Plasma Cutting Controller.
This program example is programmed in G91 Incremental programming.

What is a CNC Plasma Cutting Machine

Plasma Cutting

Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut.

CNC Plasma Cutter

A “CNC plasma” system is a machine that carries a plasma torch, and can move that torch in a path directed by CNC (Computer Numerical Control), which means that a computer is used to direct the machines motion based on numerical codes in a program.
