CNC Laser Cutting has become commonplace in the manufacturing industry, hailed for its incredible precision and flexibility. Because of its many benefits, plastic fabricators Sydney make extensive use of the technology. Many people would know how useful CNC laser cutting is, but how exactly does light cut so well? The word Laser is actually an acronym for light amplification by stimulated emission of radiation. The light in laser cutting is a heavily amplified beam, giving it the power needed to melt through solids like acrylic sheets used by plastic fabricators Sydney.
CNC laser cutting begins with computer designs of the desired part. Designs are normally produced in a CAD program and then translated using a CAM program by plastic fabricators Sydney. These translations guide the CNC machine. The machine uses a resonator to produce an intense beam of light in the head of the cutter which is focused out of the head as an incredibly thin beam using a lens. The light being so heavily focused produces a large amount of energy at the focal point which can melt or even vaporize the material. Most CNC laser cutting machines use a stream of an inert gas such as nitrogen to blow molten material out of the cut.
Laser machines are very versatile and can be used for a range of materials. Changing the focal length and depth of focus (by altering the lens or original beam) allows CNC laser cutting to be done for many material types and thicknesses.
