Laser Cutting

Overview of Laser Cutting

• Definition: Laser cutting uses a beam of laser light to generate heat for cutting metals and other materials.

Advantages of Laser Cutting

• Narrow Kerf: Produces a narrower cut compared to other thermal cutting processes.

• Reduced Heat Affected Zone: Minimizes the area around the cut that is affected by heat, reducing distortion.

• Finer Edge: Achieves smoother cuts that may require no secondary edge finishing.

• Speed: Capable of rapid contour cutting of sheet metal and drilling small holes in under a second.

Limitations of Laser Cutting

• Cost: Generally expensive, making it cost-effective mainly for thinner materials (up to 1/2 inch or 13 mm thick).

• Thickness Constraints: While able to cut thicker materials, the cost and efficiency decrease significantly with increased thickness.

Understanding Lasers

• Acronym: 'Laser' stands for Light Amplification by Stimulated Emission of Radiation.

• Coherent Light: A laser produces an intense beam of coherent light, distinguishing it from ordinary random light, which is less focused and more dispersed.
