CNC laser machining is used in a variety of materials such as aluminum and stainless steel. It creates clean edges and leaves a small heat affected zone to produce components that are stress and burr free. CNC programs for laser machining are created on computer systems from CAD drawing files

CNC machine is made up of the modules consisting of mechanic, hydraulic-pneumatic, electric, and electronic & computer. It is used to cut and shape precision products such as automobile parts, machine parts, and compressors. CNC machines include machining tools such as lathes, multi axis spindles, milling machines, laser cutting, water jet cutting, and wire electrical discharge machines (EDM), but the functions formerly performed by human operators are performed by a computer-control module. CNC machines cut away material from a solid block of metal, plastic, or glass known as a work piece to form a finished part.
