Laser cuttingis the process of using alaserbeam to vaporize, melt, or otherwise gradually remove material. Computer Numerical Control (CNC)laser cuttingcommonly uses optics, an assist gas, and a guidancesystemto direct and focus thelaserbeam into the workpiece. “the Light Amplification by the Stimulated Emission of Radiation!”Every object in the universe is made up of atoms. These atoms are constantly in motion; vibrating, moving and rotating. Atoms can be in different states of excitation; either ground state or excited level. In order for an atom (electron) to reach an excited level some type of energy must be applied via heat, light or electricity.
Once an electron moves to a higher-state, it wants to return to its original state. When it does, it releases its energy as a photon a particle of light.
These photons of light are what we use in lasers. Although there are many types of lasers, they all have certain essential features. Either a rod or a gas tube is excited by light or electricity (flash lamp, diodes or RF frequency) to release photons of light.
Laser Cutting is a non-contact process which utilizes a laser to cut materials, resulting in high quality, dimensionally accurate cuts. The process works by directing the laser beam through a nozzle to the workpiece. A combination of heat and pressure creates the cutting action.Common industrial systems (≥1 kW) will cut carbon steel metal from 0.51 – 13 mm in thickness. For many purposes, a laser can be up to thirty times faster than standard sawing.
