Abstract: This paper presents the experimental study of comparison on energy conservation during turning of lead free micro alloy steel (MAS) of cylindrical rods using K20 uncoated, single layer (TiN) coated and multi-coated (TiN-TiCN-Al2O3-ZrCN) carbide inserts. The objective of the work is to evaluate the optimised machining parameters such as cutting speed, feed rate and depth of cut, better carbide insert among the chosen and develop a mathematical model. By using response surface methodology (RSM) Based D-optimal design technique the mathematical model, the optimum cutting parameters and the best insert are evaluated. This selected approach successfully showed that the best insert with optimised machining parameters on power consumption. The results exhibited the relation between the machining parameters and the power consumption for the three types of k20 inserts. It is concluded that the experimental values and the proposed model values are in reasonable agreement.

Keywords: D-optimal method; K20 carbide uncoated and coated insert; micro alloyed steel; power consumption.
