This paper focuses on selection of cutting parameters for optimized value of response function which is surface roughness. Four parameters; spindle speed, feed, depth of cut&length to diameter (L/D) ratio of boring bar has been taken as control factors. The cutting trials are designed by using Taguchi method to deal with the response from multi-variables. Total nine trials are conducted as per 34 orthogonal array i.e. L9 & the same is repeated twice to check the consistency in output response. AISI 1041 (EN9) carbon steel is used as a job material which is cut by using standard boring bars of various sizes each having a tungsten carbide inserts of same insert radius. The surface roughness is measured at three different locations for each job & its average value is then considered for further calculation. The S/N ratio is then calculated for each response using smaller the better criteria. The optimum set of cutting parameters is selected for high value of S/N ratio. The confirmation test is then conducted to verify the parameter selection. The Analysis of Variance (ANOVA) is carried out to find the significant factors & their individual contribution in the response function i.e. surface roughness. The confirmation test results obtained satisfies the objective.

Four parameters; spindle speed, feed, depth of cut&length to diameter (L/D) ratio of boring bar has been taken as control factors. The cutting trials are designed by using Taguchi method to deal with the response from multi-variables. Total nine trials are conducted as per 34 orthogonal array i.e. L9 & the same is repeated twice to check the consistency in output response. AISI 1041 (EN9) carbon steel is used as a job material which is cut by using standard boring bars of various sizes each having a tungsten carbide inserts of same insert radius. The surface roughness is measured at three different locations for each job & its average value is then considered for further calculation. The S/N ratio is then calculated for each response using smaller the better criteria. The optimum set of cutting parameters is selected for high value of S/N ratio. The confirmation test is then conducted to verify the parameter selection. The Analysis of Variance (ANOVA) is carried out to find the significant factors & their individual contribution in the response function i.e. surface roughness. The confirmation test results obtained satisfies the objective.
