![]() Industrial laser cutting of steel with cutting instructions programmed through the CNC interface At the same time CO 2 lasers were adapted to cut non-metals, such as textiles, because, at the time, CO 2 lasers were not powerful enough to overcome the thermal conductivity of metals. In the early 1970s, this technology was put into production to cut titanium for aerospace applications. In 1967, the British pioneered laser-assisted oxygen jet cutting for metals. This machine was made by the Western Electric Engineering Research Center. ![]() In 1965, the first production laser cutting machine was used to drill holes in diamond dies. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. ![]() A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The laser optics and CNC (computer numerical control) is used to direct the laser beam to the material. Laser cutting works by directing the output of a high-power laser most commonly through optics. ![]() While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. ![]() CAD (top) and stainless steel laser-cut part (bottom) ![]()
