Abstract
Turning of hardened steel is normally carried out with copious supply of cutting fluid to improve the cutting performance. Most of the cutting fluids in regular use are petroleum based emulsions which create several environmental problems. In this context, pure dry machining is a logical alternative as it is free from the problems associated with the cutting fluid. In this study an effort was made to study the effect of flank wear and cutting temperature during hard turning of OHNS steel under dry condition. A detailed analysis was performed using Taguchi technique to find out the effect of above mentioned parameters. Analysis of Variance (ANOVA) was carried out to find out the influence of individual parameters on flank wear and cutting temperature. Confirmation tests were performed to compare the predicted values with the experimental values and it was found that the results matched well with the experimental results
