Keywords:
Hard turning, EN36, Chip reduction coefficient, ANOVA, Taguchi method.Abstract
In the present study, experimental investigation of the effects of the various cutting parameters on the chip reduction coefficient in the hard turning of EN 36 steel is done. The cutting parameters selected for the work was the feed, cutting speed and depth of cut. The objective of the present work is to minimise the chip reduction coefficient which helps to minimise the cutting forces and vibrations. Taguchi L9 orthogonal array is used to design the experiment and smaller the better is selected to find out the most significant parameter. Analysis of variance was used to do the analysis of the results obtained in the experiment. The percentage contribution of the cutting parameters was calculated using 95% confidence value. From the analysis of the results, it is observed that the depth of cut is the most significant parameters with 49.82 % contribution value and is followed by feed at 20.26 % contribution value.
