The power is supplied to the system for exiting the electron. Work piece is like the object in which the operation is to be carried out. LASER (light amplification by stimulated emission of radiation) is basically a coherent and amplified beam of electromagnetic radiation. The laser light has maximum temperature strikes on the workpiece, due to high temp the workpiece gets melts. Laser cutting is a technology that uses a laser to slice materials. This framework discovers its fine application in cutting out things from fragile materials with low conductivity. Laser beam machining (LBM) is a non-conventional Machining manufacturing process, a form of machining, in which a laser is directed towards the work piece for machining. A high-energy laser beam focuses on a workpiece or component, and the thermal energy transfers to the targeted surface. By 1967, CO 2 lasers with power exceeding 1,000 watts were possible.
