Laser Beam Machining Definition

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 ablation or photoablation is the process of removing material from a solid or occasionally liquid surface by irradiating it with a laser beam.

Laser beam machining definition. 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. The term laser originated as an acronym for light amplification by stimulated emission of radiation. The process used thermal energy to remove material from a metallic surface. Laser beam machining is a non conventional machining method in which the operation performed by the laser. The laser stand for light stimulated emission of radiation. A laser beam used for welding red 660 635 nm green 532 520 nm and blue violet 445 405 nm lasers a laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. At high laser flux the material is typically converted to a plasma. The processes can include laser drilling cutting grooving writing scribing ablation welding cladding milling and so on. Laser beam machining working principle. The laser optics and cnc computer numerical control are used to direct the material or the laser beam generated. Maiman and it has since then been developed into various fields of applications eg production engineering medicine. On this channel you can get education and knowledge for general issues and topics. Laser beam machining lbm is a nonconventional machining process which broadly refers to the process of material removal accomplished through the interactions between the laser and target materials. 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. By rajnish bhusal department of mechanical engineering ritm 2.

The term laser is an acronym for the physical effect light amplification by stimulated emission of radiation but is often also used to refer to the beam source. 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. The first laser was demonstrated in 1960 by th. The first laser was built in 1960 by. At low laser flux the material is heated by the absorbed laser energy and evaporates or sublimates. Plasma arc machining 1. The working principle of laser beam. This process uses thermal energy to remove material from metallic or nonmetallic surfaces.
