 | How Laser Cutting Works |
| Design Input (CAD File) The process starts with a digital design made in software like AutoCAD, SolidWorks, or Illustrator. The file is converted to a format the laser machine can read (DXF, SVG, or G-code) | |
Laser Generation A laser source (like Fiber, CO₂, or Nd:YAG) generates a high-intensity beam of light. The beam is directed via lenses and mirrors to a focused point on the sheet material. | |
| Material Cutting The focused laser beam hits the material with intense energy. It melts, burns, or vaporizes the metal, while a stream of assist gas (usually nitrogen, oxygen, or air) blows away the molten metal. | |
| Motion & Precision The cutting head moves based on the programmed path, guided by a CNC system (Computer Numerical Control). The kerf (cut width) is very narrow—often between 0.1 mm to 0.5 mm, enabling intricate designs. | |
| Assist Gas Oxygen: Used for cutting thick mild steel, increases cutting speed. Nitrogen: Used for stainless steel and aluminum to avoid oxidation. Air: A cheaper alternative for low-cost cutting. | |
| Result Produces clean edges, high accuracy, and minimal post-processing. Ideal for complex shapes, small holes, and sharp corners. |
| Type of Laser | Best For | Description |
| CO₂ Laser | Non-metal and light metals | Good for plastics, wood, thin metals |
| Fiber Laser | Metals (steel, aluminum, copper) | High energy efficiency, longer lifespan |
| Nd:YAG Laser | Precision engraving/cutting | Great for fine detail, often used in electronics |
