A laser beam with a high energy density provides highly targeted heating on a workpiece in the Laser Beam Machining method. The material is caused to melt, vaporize or ablate in order to remove the material from the piece at micron level. It is an energy-less thermal beam based non-contact tool with several unique filexlib. Laser (light amplification by stimulated emission of radiation) is a coherent and amplified beam of electromagnetic radiation. The key element in making a practical laser is the light amplification achieved by stimulated emission due to the incident photons of high energy. b) Laser Beam Machining. c) Light Blast Manufacturing. d) Light Beam Machining.

Laser beam machining (LBM) is a form of machining that uses heat directed from a laser beam.This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high frequency of monochromatic light will fall on the surface, thus heating, melting and vaporizing the material due to the impinge of photons (see Coulomb explosion). Laser beam machining is best suited for
Laser beam machining (LBM) is a form of machining that uses heat directed from a laser beam. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high frequency of monochromatic light will fall on the surface then heating, melting, and vaporizing of the material take place due to impinging of photons.

Abstract. Laser beam machining removes, melts, or thermally modifies a material by focusing a coherent beam of monochromatic light on the workpiece. This article describes the principal lasers used in metal processing: neodymium-glass, carbon dioxide, and neodymium-doped yttrium aluminum garnet lasers. It discusses the operating parameters of
Electron Beam Machining Diagram©2022 MechanicalEnotes.com 7. LBM (Laser Beam Machining) Process: When the power supply is given to the laser gun it is producing very high-intensity electromagnetic waves in the form of a beam called a laser beam with a wavelength ranging from 0.1 to 70 micrometers.
Laser beam machining (LBM) is one of the foremost widely used thermal energy-based non-contact kind advanced machining methods that may be applied for nearly a whole variety of materials. ray of light is focused on melting and vaporizing the unwanted material from the parent material. it's appropriate for geometrically advanced profile cutting and creating miniature holes in flat solid.
Working Principle of Plasma Arc Machining. The principle of plasma arc machining is shown in the figure. In a plasma torch, known as the gun or plasmatron,
