Laser Beam Machining By Himanshu Vaid

Background laser stands for light amplification by stimulated.

Laser beam machining schematic diagram. Schematic diagram of laser beam machining centre. Schematic diagram of lbw 8. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. 5 the unreflected light is absorbed thus heating the surface of the workpiece. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Laser beam machining working principle. The laser beams are focused to the cavity between the two metal pieces to be joined. On sufficient heat the workpiece starts to melt and evaporates. After the experiments were conducted according to taguchi l9 orthogonal array surface roughness test was carried out on the cutting edge using tally surf mitutoyo made suftest sj 210 value of ra is tabulated. Schematic diagram of laser beam machine figure 4. 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. Laser beam machining lbm. Experimental process layout. Laser beam machining is a non conventional machining method in which the operation performed by the laser. 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.

The laser stand for light stimulated emission of radiation. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Schematic diagram of laser beam machine figure 4 17 material removal mechanism in lbm figure 5 physical processes occurring during lbm 18. The laser optics and cnc computer numerical control are used to direct the material or the laser beam generated. The working principle of laser beam. Heat treatment of metals powerpoint jutka. Mechanics of lbw laser beam welding lbw is a welding process which produces coalescence of materials with the heat obtained from the application of a concentrate coherent light beam impinging upon the surfaces to be joined. As presented in fig. The physics of laser machining is very. 5 the unreflected light is absorbed thus heating the surface of the workpiece. The laser beams have enough energy and when it strikes the metal pieces produce heat that melts the material from the two metal pieces and fills the cavity. A commercial laser for cutting materials involved a motion control system to follow a cnc or g code of the pattern to be cut onto the material. Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser. The process used thermal energy to remove material from a metallic surface. Material removal mechanism in lbm figure5 physical processesoccurring duringlbm as presented in fig.
