Laser cutting is a technology that uses laser light to cut materials, typically used in industrial manufacturing applications, but is also beginning to be used by schools, small businesses, and hobbyists. Laser light cutting works by directing the output of a high-power laser device through an optical system. The laser light used in laser light cutting is controllable monochromatic light with high intensity and high energy density. It can produce huge power density through focusing through the optical system. CNC (Computer Numerical Control) is used to guide the material or the generated laser beam, making high-energy The laser beam is irradiated on the part of the workpiece to be processed to complete the processing. A typical commercial laser used to cut materials involves a motion control system that follows CNC or G-code for the pattern to be cut into the material. A focused laser beam is directed at the material, which then melts, burns, vaporizes, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. Industrial laser cutting machines are used to cut flat sheet materials as well as structural and piping materials. .
The light intensity of laser light is very high, and it can process almost all metal and non-metal materials. It can process not only high hardness and high melting point materials, but also brittle and flexible materials. Since laser processing is non-contact processing, there is no need to use metal cutters or abrasive tools when working.
