Laser cutting is mostly a thermal process in which a focused laser beam is used to melt material in a localized area. A co-axial gas jet is used to eject the molten material from the cut and leave a clean edge. A continuous cut is produced by moving the laser beam or work piece and leave a clean edge. A particular characteristic of a laser cut is the formation of striations on the cut edge. These striations play an important part in laser cutting as they effectively control the edge roughness. Laser Beam Machining is widely used manufacturing technique utilized to perform cutting, engraving and welding operations on a wide variety of materials ranging from metals to plastics. In the present work an attempt has been made to study the effect of process parameters such as feed rate, input power and standoff distance on the quality of the machined surface using laser beam on mild steel and stainless steel. The quality of cut is assessed in terms of response parameters such as upper kerf width, lower kerfs width, taper of the cut surface and surface roughness. Design of experiments is implemented by using a full factorial design. The effect of the process parameters on response have been shown by means of main effect plots developed using ANOVA analysis. After Design of Experiment (DOE) by using full factorial method, the analysis will be carry by the ANalysis of VArience (ANOVA) method.
