Abstract—Surface roughness is an important factor for ensuring the dimension geometry is within the permitted tolerance. The ideal surface roughness is determined by optimal turning parameter of EN-8 steel cylindrical rods. EN-8 steel finding many applications such as shaft, axle, gears and Fasteners due to their high hardness, strength to 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-8 steel with different parameters such as cutting speed, feed and depth of cut are greatly influenced by response parameters. The experimental design was formed based on Taguchi’s Technique. An orthogonal array and Analysis of Variance (ANOVA) are employed to investigate the Turning conditions and machining was done using coated tool insert.
