In Manufacturing sector Turning is the most common process used to remove material from cylindrical workpiece & produce smooth surface finish on the workpiece. In turning process Material removal rate & Surface roughness are the important performance characteristics to be considered which is affected by several factors such as spindle speed, cutting tool material, feed rate, depth of cut, Nose radius cutting tool, coolant and work material characterstics. Alloy Steel EN-24 is a medium carbon steel which is used in manufacturing of aircraft Automotive & axles components, Heavy duty Gears, Shafts, Spindles, Studs, collets, Pins, bolts, sprockets, couplings, pinions & pinion arbors. In this research Response surface methodology (RSM) was applied to determine the optimum machining parameters leading to minimum surface roughness maximum MRR in turning process. In this research spindle speed, depth of cut & feed rate are considered to be main parameters for turning on Alloy Steel. Through multi response optimization the optimum value of the surface roughness (Ra) comes out to be 1.46389 ?m for MRR is 403.458 mm3/sec. It is also concluded that feed rate & depth of cut are the major significant factor affecting surface roughness & MRR.
