Laser Beam Machining By S Premkumar Ppt Video Online Download

Working principle the laser beam is focused onto the work piece and can be moved relative to it.

Laser beam machining ppt slideshare. Laser beam machining welding. Laser material interactions a great advantage of laser machining is capability to machine any kind of material not necessarily conductive depending on laser intensity and interaction time. Lbw is a versatile process capable of welding carbon steels hsla steels stainless steel aluminum. In contrast to some other processes laser operates using high energy photons therefore there is not a typical tool as the laser beam directly targets. In thermal removing processes thermal energy provided by a heat source melts or vaporizes the volume of the material to be removed. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Gambar diagram skematik dari proses abrasive jet machining abrasive jet machining ajm menggunakan aliran butiran abrasive halus dicampur dengan udara atau gas pembawa lainnya pada tekanan tinggialiran ini diarahkan oleh nosel yang didesain cocok untuk keperluan tersebut kepada permukaan benda kerja yang. Electron beam machining powerpoint ppt presentations. Properties of laser a. Effect of laser beam on material 6 source. Introductions 1laser beam machining lbm is a non traditional subtractive manufacturing process a form of machining in which a laser is directed towards the work piece for machining. Electron beam ebm and laser beam machining lbm are newer. Electron cloud and beam beam effects in particle accelerators. The electrons of these atoms move to a higher orbit then release photons creating a laser beam. Laser beam machining prepared by shimagiri vykuntam 14a51a0395 1 2.

A laser beam is a powerful narrow monochromatic and directional beam of electromagnetic radiation often these beams are within the visible spectrum of light a laser device excites the atoms in a lasing medium. What is laser laser stands for light amplified stimulated emission of radiation laser is a device which generates or amplifies light stimulated emission of electromagnetic radiation coherent monochromatic directional and high power laser beam is used 2. Lbm is nontraditional thermal process. 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 1. It is a non conventional machining process in which no tool is used. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. The laser machining process is controlled by switching the laser on and off changing the laser pulse energy and other laser parameters and by positioning either the work piece or the laser focus. It is used to machine both metallic and non metallic material. A laser machine consists of the laser mirrors for.
