Abstract—Recently EN-9 steel finding many applications like shaft, 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 EN-9 steel 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 with different cutting parameters of EN-9 of turning parameters and optimized by S/N ratio and analyzed by Analysis of variance (ANOVA’s).
