Experimental analysis of heat affected zone by laser beam machining

Abstract

LASER stands for Light Amplification by Stimulated Emissionof Radiation. Laser-beam machining is a modern, subtractive, thermal material-removal process that utilizes a high-energy, coherent, high intensity beam of light beam to melxt and vaporize particles on the surface of metallic and non-metallic workpieces. Lasers can be used to cut, drill, weld and mark and to make complex job profiles which requires accuracy and precision. Laser also has many medical uses (like in dental industry, surgery, cancer treatment, etc.). This modern technology is finding ways to integrate into daily life with a purpose of easing our work. The main aim of this paper is to study briefly about Laser Beam Machining with parameters included as this paper touches the very key points of working, existence, uses, types and their usage with their respective lifespan.
