Mrr in laser beam machining. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. In lbm surface roughness is one of important response which affects the quality characteristics of product. Thermal imaging has already been applied for some laser machining processes like laser welding 20 and laser cladding 3. Like a beam of high velocity electrons a laser beam is also capable of producing very high power density. 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. It is used to machine both metallic and non metallic material. Mrr for laser machining is not limited by constraints such as maximum tool force built up edge formation or tool chatter. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process which can be applied for almost whole range of materials. Laser beam machining lbm is one of the advanced machining processes which are used for shaping almost whole range of engineering materials. Lbm is a exible. 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. The main advantages of laser beam machining are ease of automation for complex cutting patterns absence of tool wear and.

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. Laser beam machining lbm. Laser beam machininga review avanish kumar dubey vinod yadava department of mechanical engineering motilal nehru national institute of technology allahabad 211004 up india. Laser is a highly coherent in space and time beam of electromagnetic radiation with wavelength varying from 01mm to 70mm. Sensors may be positioned off axis to the primary laser beam figure 2 a. Thermal or near ir imaging for monitoring and feed back control in laser machining. 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. 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.
