Efficiency Of Laser Beam Machining

This paper provides an overview of the environmental performance energy and resource efficiency of different types of laser cutting systems and derived performance improving strategies. 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.

To improve the wetting quality of water film on workpiece surface organic additives are added.

Efficiency of laser beam machining. This will depend on type of laser and how well the laser is matched to the work at hand. One considering the entire laser system and the other including only the workpiece laser beam interaction. Laser fluence pulse energy and beam spot size beam scanning speed pulse repetition rate and scanned line hatch distance for the copper sample. It is used to machine both metallic and non metallic material. Industrial laser efficiency may range from 5 to 45. In this post you learn what is laser beam machining its working principle parts advantages applications and limitations. High throughput laser micro machining demands precise control of the laser beam position to achieve optimal efficiency but existing methods can be both time consuming and cost prohibitive. The laser is electromagnetic radiation. The laser machining energy efficiency is investigated under two different analyses boundaries. 752 material removal mechanism of nanosecond pulsed laser beam cutting at submerged condition. 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. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. For the case of the workpiece laser beam interaction problem the laser drilling process has been selected as the most typical application. 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. Selection and blind review under responsibility of the bayerisches laserzentrum gmbh.

Solid state lasers with pulse duration of 10 ps and radiation wavelength of 1064 nm were used to investigate the laser ablation efficiency dependence on processing parameters. Published by elsevier bv. The power consumption and efficiency of any particular laser will vary depending on output power and operating parameters. Ac 2014 the authors. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Sometimes water solution of salts or bases or acids are used during submerged laser beam machining to improve the etch rate and finish quality. It is a non conventional machining process in which no tool is used. Laser beam machining is a thermal machining process which uses laser beam to produce heat. The main disadvantage of laser cutting is the high power consumption. 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.
