The Six Sigma practice is applied to increase the quality of the machined surface and in this work six sigma practice is usedto determine the optimal level of parameters. Six sigma technique is combine with Taguchi technique for optimizing theturning process parameters. Mild steel is used as a work piece to optimize the material removal rate. The primary objectiveof this research work is maximizing the material removal rate during turning of mild steel using single point cutting tool. Theturning process parameters considered in this work are cutting speed, feed rate and depth of cut. The optimal parameterscombination for signal to ratio values for turning process is A3-B4-C2, which gives cutting speed as 1000rpm, feed rate 0.20mm/rev and depth of cut 0.8mm. The validation experiments are also conducted and the optimal turning parameters areobserved to provide maximum material removal rate.
