Among several industrial manufacturing operations, milling is a fundamental machining operation. In that, end milling is the most common metal removal operation used. In this paper, a number of experiments for the end milling operation have been performed to get an idea about the surface quality on material. The aim of this research is to have a better knowledge of the effect of machining parameters such as speed, feed and depth of cut. Here in this study, Design Expert software was used and

The effect of speed, feed and depth of cut for predicting surface roughness was considered in this study and interactions between two variables are also studied. The equation in terms of actual factors was also generated and after using analysis of variance (ANOVA), optimization was done to find out the best value. It was observed that feed and speed are significant when minimization of surface roughness is considered.
