experimental analysis of cnc turning of nylon using taguchi method

manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. the material removal rate is a significant indicator of the productivity and cost efficiency of the process. taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering three important cutting parameters like cutting speed, feed rate and depth of cut during machining on cnc. the objective of the paper is to find out, which process parameters having more impacts on material removal rate during turning operation on nylon using analysis of variance (anova). an orthogonal array has been constructed to find the optimal levels of the turning parameters and further signal-to-noise (s/n) ratio has been computed to construct the analysis of variance table. the results of anova shown that feed rate has most significant factor on mrr compare to cutting speed and depth of cut for nylon. the confirmation experiments have conducted to validate the optimal cutting parameters and improvement of mrr from initial conditions is 555.56%.
