Abstract: This article presents the experimentally comparison on machining of micro alloyed steel (MAS) of cylindrical rods with 80 mm diameter and length of 350 mm using the medium-duty lathe of 7.5 kW spindle power at 1,600 rpm to set the guide lines and to understand the machining behaviour of MAS using K20 uncoated, single layer (TiN) coated and multi-coated (TiN-TiCN-Al2O3-ZrCN) carbide insert. The mathematical modelling and optimum cutting parameters have been identified by response surface method (RSM)-based D-optimal design technique. Significant contribution of parameters can then be determined by analysis of variance (ANOVA). Experimental results have shown that surface roughness performance can be improved effectively through this approach. The results shown the relation between the machining parameters such as cutting speed, depth of cut and federate on surface quality and also the role of cutting parameters on cutting force. It is concluded that, the experimental values are in reasonable concord with the proposed model values. The proposed model and analysis is very effectual in the turning operation of micro alloy steel.
