Abstract—Oil Hardened Non Shrinkable steel (OHNS) rods finding many applications like Lay shafts, Wheel axle, gears and Fasteners Due their high hardness, strength and weight ratio. Optimum machining parameters of turning operations are greatly influenced with concern along with manufacturing environment. In this experimental work turning parameters on OHNS with different cutting parameters like cutting speed, feed and depth of cut greatly influenced by response parameters like surface roughness and metal removal rate. Mainly surface roughness where investigated employing L9 orthogonal array using taguchi’s design of experiments. The different cutting parameters of OHNS of turning parameters and optimized by S/N ratio and analyzed by Analysis of variance (ANOVA’s).
