Abstract: The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is capable of estimating the tool wear at different cutting conditions. The central composite design has been used to plan the experiments. Coated carbide inserts have been used for turning EN 31 alloy steel. Results revealed that cutting speed is the most significant factor effecting flank wear, followed by depth of cut and feed rate. Flank wear increases with increase in all the three cutting parameters.
