Laser Beam Machining is one of the mostly use manufacturing technique utilized to perform cutting, engraving and welding operations on a variety of materials like metals, plastics, ceramics etc. CO2 laser cutting is mostly used for sheet metal cutting. The present work is to study the effect of process parameters of CO2 laser cutting such as cutting speed, input power and gas pressure on the quality of the machined surface using laser beam on stainless steel SS 409. The quality of cut is measured in terms of response parameters such as kerf width and surface roughness. Design of experiments is implemented by using a Taguchi method design. The effect of the process parameters on response have studied by means of main effect plots which are developed by using ANOVA. After Design of Experiment (DOE) by using Taguchi method, the analysis is carried by the Analysis of Variance (ANOVA) method.& optimum parameter is selected on the basis of the signal to noise ratio.
