Title

AN OVERVIEW: MACHINING TECHNOLOGY BY STIMULATED EMISSION OF RADIATION

Abstract

Abstract – Albert Einstein first published the key principle behind the operation of the laser [light amplification by stimulated emission of radiation], when he hypothesized that, under the proper conditions, light energy of a particular frequency could be used to stimulate the electrons in an atom to emit additional light with exactly the same characteristics as the original stimulating light source. Lasers are considered to be the advanced material processing tools filling the gap in the precision, low cost, localized processing, and high speed of operation. The laser is electromagnetic radiation. It produces monochromatic light which is in the form of an almost collimated beam that can be focused optically on to very small spots of less than 0.002 mm diameter. In laser machining applications, a laser beams used as a heat source increasing temperature rapidly to the melting and evaporation temperature of the substrate material. Since the arrangements of the optical setting for the laser beam are very precise, the localized heating can be controlled easily. With recent advancement in laser technology and computations power, laser machining application has become almost an integral part of the aerospace, power, electronics, and sheet metal forming industries. However, in laser machining operations, the physical processes are complicated and they require deep understanding of process to secure improved end product quality
