摘要：Laser machining is a popular manufacturing process utilized to cut various types of materialseconomically. In this project CO2 laser machining of Mild Steel has been investigated. Mild Steel is soft because of itshigh strength and malleability. The width of laser cut or kerf, quality of the cut edges are affected by laser power,machining speed, assist gas pressure, and stand-off distance between nozzle and the work piece material. Theexperiment was designed and carried out on the basis of standard L16 Taguchi’s orthogonal array in which the fourlaser machining parameters were arranged at Four levels. From the analysis of mean values of variance, the significantlaser machining parameters were identified. The Machining Time reduces with significantly with decrease in Powerand Cutting Speed .The Surface Roughness decreases with the increase in Power, Cutting Speed, and Stand Offdistance. The Hardness of the material increases with the increase in Power and at low Stand Off Distance. The KerfWidth is reduced with the increase in Power and Cutting Speed
