Laser beam machining is a thermal energybased advanced machining process in which material is removed by focusing the laser beam on the work surface at a constant distance to melt and vaporize the unwanted work material.

Thermal features of laser beam machining. The high frequency of monochromatic light will fall on the surface then heating melting and vaporizing of the material take place due. Generated at the contact of the workpiece surface with a. The laser beam is. The laser optics and cnc computer numerical control are used to direct the material or the. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. It is a non conventional machining process in which no tool is used. Generation and control of electron beam for machining theory of electron beam machining comparison of thermal and non thermal processes. The main advantages of laser beam machining are ease of automation for complex cutting patterns absence of tool wear and. The light produced is a coherent monochromatic and collimated beam which can be focused to small spots of diameter of 0002 mm. Laser cutting is a technology that uses a laser to cut materials and is typically used for industrial manufacturing applications but is also starting to be used by schools small businesses and hobbyists. Laser beam machining laser cutting heat affected zones kerf width assist gas introduction acroynam of laser is light amplification by stimulated emission of radiation. Laser beam machining is a form of non traditional machining that can machine almost any known materials. Table 1 presents specifications of the laser beam. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Laser beam machining lbm is a form of machining process in which laser beam is used for the machining of metallic and non metallic materials.

Type of laser beam is a co2 laser and gaussian beam. It is used to machine both metallic and non metallic material. General principle and application of laser beam machining thermal features cutting speed and accuracy of cut. The laser beam is used to heat workpiece before the material is removed. 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. Cutting temperature and laser beam temperature effects on cutting tool. Laser beam machining thermal effect melting vaporizing laser beam grooving work speed 1 introduction enough but able to affect the surface layers of the metallic workpieces processes of heat treatment could the laser beam manufacturing is based on the effects be applied. In this process a laser beam of high energy is made to strike on the workpiece the thermal energy of the laser gets transferred to the surface of the wp workpiece. Laser cutting works by directing the output of a high power laser most commonly through optics. This process uses thermal energy to remove material from metallic or nonmetallic surfaces.
