This process uses thermal energy to remove material from metallic or nonmetallic surfaces.
Laser beam machining cost. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Background laser stands for light amplification by stimulated. 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. It produces monochromatic light which is in the form of an almost collimated beam that can be focussed optically on to very small spots of less than 0002 mm dia. 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. The laser is electromagnetic radiation. In this post you learn what is laser beam machining its working principle parts advantages applications and limitations. Chinmay pamecha 2009ume453 presentation overview background laser cutting fundamentals types of lasers equipment material removal mechanism by laser process parameters application laser beam selection guide comparison with other methods cost advantages and limitations new developments safety hazards references. The high frequency of monochromatic light will fall on the surface then heating melting and vaporizing of the material take place due. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Laser beam machining lbm is a thermal energy based advanced machining process in which the material is removed by i melting ii vaporization and iii chemical degradation chemical bonds are broken which causes the materials to degrade.
