Advantages of laser cutting over mechanical cutting include easier workholding and reduced contamination of workpiece since there is no cutting edge which can become contaminated by the material or contaminate the material.

Laser beam machining process. Application of laser beam machining. The laser cutting process involves focusing a laser beam usually with a lens sometimes with a concave mirror to a small spot which has sufficient power density to produce a laser cut. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Precision may be better since the laser beam does not wear during the process. The laser machining process is at present found to be suitable only in exceptional cases like machining very small holes and cutting complex profiles in thin hard materials like ceramics. The laser stand for light stimulated emission of radiation. It is used to machine both metallic and non metallic material. The laser is light amplification by stimulated emission of radiation and laser beam machining is a non traditional way of manufacturing. The working principle of laser beam. Laser beam machining is a non conventional machining method in which the operation performed by the laser. In fact its a subtractive manufacturing process in which a laser beam is used for cutting through the metals and other materials for getting the desired product. It is a non conventional machining process in which no tool is used. 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 beam machining lbm is a form of machining process in which laser beam is used for the machining of metallic and non metallic materials. Laser beam machining or lbm is a non contact industrial procedure wherein the material that is processed is physically left untouched while using laser beam to melt or vaporize unwanted materials from a workpiece.

The process used thermal energy to remove material from a metallic surface. Laser beam machining used light energy from a laser to remove material by vaporization and ablation energy is concentrated optically laser emits either continuous or pulsed light beam 5 source. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. Laser beam machining working principle. The lens is defined by its focal length which is the distance from the lens to the focused spot. 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. Effect of laser beam on material 6 source.
