A laser cutter is a device that creates patterns, shapes, and designs in materials such as wood, glass, paper, metal, and plastic by cutting into them with a high-power laser—the precision by which a laser makes for a clean cut and smooth finish. Laser cutting has been used for many decades in large-scale manufacturing, but more recently, it has become more affordable and is increasingly used by hobbyists, schools, and small businesses.
Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While it is mostly mainly used for industrial manufacturing applications, it is also used by schools, small businesses, architecture, and hobbyists. Laser cutting works only by directing the output of a high-power laser mainly through optics. The laser optics and CNC (computer numerical control) direct the laser beam to the material surface.
There are mainly three main types of lasers which. Most of the three main types of lasers are used in laser cutting. The CO2 laser is suited for cutting, boring, and engraving. The neodymium (ND) and neodymium yttrium-aluminum-garnet lasers are very much identical in style and differ only in their application.
Methods in laser cutting machine
Several methods are used in cutting with the help of lasers, with different types used to cut other materials. Some methods include vaporization, melt and blow, melt and burn, thermal stress cracking, scribing, cold cutting, and burning stabilized with laser cutting.
There are generally three industrial laser cutting machine configurations: moving material, hybrid, and flying optics systems. These all refer to the part where the laser beam is moved over the material so that it is cut thoroughly. For all these, the axes of motion are typically designed and named the X and Y axes. If the cutting head can be controlled, it is named the Z-axis.
Advantages of laser cutting machine
- Cuts non-ferrous material with ease.
- It is reliable and fast machinery for rapid turnaround.
- It uses significantly less energy while cutting, using nitrogen, oxygen, and air.
- It can cut through the thickest parts of metals which include mild steel.
- Cut complex shapes with precise detail.
Purpose of laser cutting
Laser cutting is a method of cutting shapes or designs into a metal sheet or other structural materials primarily used in the manufacturing industry. Still, it is also growing in popularity among other sectors, such as schools and hobbyists.
Laser cutting is a fabrication process that employs a focused, thin laser beam to create shapes, patterns, and fully customized designs. One real plus is that this process can produce delicate, complex parts without needing a custom-designed tool.
