Optimization of Laser Beam Machine for AISI-1040 Material using Taguchi Methodology

Abstract

There are various input parameters that affects the laser cut but most widely input parameters which affects surface roughness and kerf taper are Laser Power, Gas Pressure, Cutting Speed. Optimization is done by "Taguchi Methodology". The Taguchi methodology involves reducing the variation in a process through robust design of experiment. It works mostly when there are intermediate number of variable (3-5) and when only few variables contribute significantly. The research paper tells us the optimum characteristics of surface roughness and kerf taper by using "Minitab" software. It also tells us about new trends and future scope of "LBM". Cutting parameters are adjusted such a that provide the quality of cut desired. In this research work input parameters are taken as Cutting Speed, Gas pressure, laser powers are studied. Simultaneously their optimum set is analyzed by using Taguchi Methodology from Minitab software for Surface Roughness and Kerf taper as output Parameter for the AISI-1040 Material.
