Abstract: In recent year’s traditional grinding process are being replaced by hard turning for the finishing operation of hardened steel. High rate of TW and the cost of CBN inserts associated with hard turning is a cause of concern. In order to minimize the TW, this work proposes the optimal cutting conditions for the hard turning of Hardened AISI 4140 steel (47 HRC) utilizing low affluent CVD coated Ti(C, N) + Al2O3 carbide tool. All the trials are conceded out based on Design of Experiments. Response surface methodology based on BBD is followed for experimentation. The ANOVA is utilized to recognize the most impacting parameters on the TW. Results indicate that both the CS and the DoC influences the TW. Optimization results reveal lower CS results in minimal TW.
