Optimization of CNC Lathe Machining Parameters by Using Taguchi Method

Abstract

This paper is about the Optimization of CNC lathe Machining Parameters such as Speed, Feed, Depth of Cut,
by using TAGUCHIMethod to improve the quality of manufactured product. TAGUCHI orthogonal array is generated
with the three levels of turning parameters by using MINITAB 19 software. In this Study, The Material Removal Rate,
Tool Wear Rate is taken as the quality characteristic output with the concept of Larger The Better and Smaller The Better
respectively. TAGUCHI method gives the importance of analyzing the response variation using the Signalto Noise Ratio
or (S/N) Ratio. The signal to noise ratio for the larger the better for MRR and smaller the better for TWR. The signal to
noise ratio values are calculated by taking consideration by using the software MINITAB19. The M.R.R, TWR values are
measured from the analysis and their optimum value for maximum removal rate also measured. Aluminium is used as the
work piece material for experimentation to optimize the M.R.R. and T.W.R. ANOVA(Analysis of Variance) was employed
along with Signal To Noise Ratios to determine the optimum values for MRR and TWR.
