Plasma cutting has become a vital technique in modern manufacturing, and understanding G-code for plasma cutting is essential for precision and efficiency. G-code is the programming language that guides CNC plasma machines, defining the movements, speeds, and cutting sequences.
Key Functions of G-code in Plasma Cutting
- G00: Rapid positioning – moves the plasma torch quickly to a specific coordinate.
- G01: Linear interpolation – allows cutting in a straight line at controlled feed rates.
- G02 / G03: Circular interpolation – enables smooth curved cuts clockwise (G02) or counterclockwise (G03).
- M03 / M04: Spindle/torch control – starts or stops the plasma arc.
Important Parameters for Plasma Cutting
Optimizing cutting quality depends on the correct use of G-code parameters:
- Feed Rate (F): Controls the speed of the torch to avoid uneven edges.
- Cutting Height (Z-axis): Maintains proper distance between torch and material.
- Pierce Delay (P): Sets the pause time for the arc to stabilize before moving.
- Kerf Compensation: Adjusts for material width to ensure precise dimensions.
Tips for Efficient Plasma Cutting
Using G-code optimization techniques, such as minimizing rapid moves and adjusting feed rates, ensures cleaner cuts and extends consumable life. Additionally, simulation software can verify paths before actual cutting, reducing errors and material waste.
Mastering G-code for plasma cutting allows operators to achieve accurate, high-quality cuts consistently while improving productivity and reducing material costs.
