How Does Laser Cutting Work?

In CNC (computer numerical control) laser cutting, a computer directs a high-powered laser to cut a specified shape from sheet metal or other material. The focused laser burns away, melts, or vaporizes the material, leaving the desired shape behind. Laser cutting creates precision cuts and smooth edges at faster speeds than other cutting techniques. CNC laser cutting is also more environmentally-friendly than some other cutting methods, using less energy, and producing less material waste.

Applications for Laser Cutting

CNC Laser cutting of metal

Laser cutting provides a fast, accurate and provides a high quality cut for appropriate materials. There is a low set up time relative to other cutting methods. This allows for competitive pricing even at lower quantities.

Laser cutting is well suited for mild steel (including pre-plated steels like galvanized steel), stainless steel, aluminum. Brass and copper can be handled by fiber optic laser cutting.

Laser Cutting Considerations

Extremely small features may not cut well. A good rule of thumb is that no feature should be smaller than the thickness of the material. The same rule applies to the distance between features or cut lines of any other variety.

Pros and Cons of Fiber Optic vs CO2 Laser Cutting

Fiber Optic Laser Cutting

Fiber optic laser cutting is preferable where thinner material needs to be cut. The speed is much greater on thin sheet metal with fiber optics than with CO2 laser cutting. Fiber optic laser cutting is also used for copper and brass, as there is less chance of back reflections causing damage to the CNC machine. Thicker plates of sheet metal can also be processed and cut efficiently.

Where CO2 laser cutting has an advantage is in the cutting speed of thicker materials, typically above 13/64″. CO2 laser cutting also can go faster in a straight line, with a faster piercing times at the beginning of the cut. When cutting thicker sheet metal, CO2 cutting can also result in a smoother surface finish vs fiber optic laser cutting.
