Laser Cutting
Laser cutting produces part shapes by cutting sheet material using an intense laser beam. This cutting method uses a beam of high-density light energy focused through a tiny hole in a nozzle.
About Laser Cutting
MaterialsSeveral materials are applicable. Aluminum can be laser cut but requires a higher power more expensive laser. Stainless steel, plain steel and spring steel are highly suitable. Metals such as copper alloys are difficult due to their ability to reflect the laser light and absorb heat. Many plastics are problematic due to toxic fumes.
Design Considerations
Sharp inside corners of the part may have a slight rounding due to beam radius of approximately 0.02 – 0.04".
Edge burrs are usually minimal and debarring of edges is usually not necessary.
Thin flimsy structures, such as shapes where a high percent of material is removed and long slots may experience some warping.
Advantages
The process offers low cost for prototype and short runs since no physical tooling is needed. Heat distortion is minimal and typically limited to about 10% of material thickness. Cut parts generally remain flat. Lasers leave minimal burrs.
