Abstracts: Surface finish is an important parameter of the milling operation in manufacturing process. Our Objective is to optimize surface roughness using Taguchi method. Taguchi method can effectively determine the best cutting parameters value for a specific cutting condition in milling operation and can achieve minimum surface roughness. In this study, the experimental results corresponding to the effects of different feed rates, different cutting speeds and various depth of cuts, on the surface quality of the M.S material work piece turned on industrial production on VMC machine have been investigated using Taguchi method. Minitab is used to establish the relationship between the surface roughness and the cutting input parameters (Cutting speed, feed and depth of cut). The Experimental work identifies minimum surface roughness value at certain combination of cutting parameters. Minitab is used for graphical analysis of result obtained by experimental work. That displays effect of feed, cutting speed and depth of cut on surface roughness. Surface roughness increases when depth of cut increases. Surface roughness decreases when cutting speed increases. Surface roughness increases slowly as feed rate increases. Tungsten Carbide tool is used inVMC machine. Numbers of experiments are performed on VMC machine and roughness tester measures surface roughness values of material. This result is compared to result obtained by Taguchi method. Taguchi method is best method for optimization process.
