Study on Influence of Process Parameters on Surface Roughness in CNC Milling Operation

Machine tools are a vital element in engineering manufacturing environment. It assists in the supply of products and components that meet the highest possible standards. An experimental approach was administered to evaluate the factor affecting surface finish in milling operation performed on ferrous material under wet cutting condition. Laboratory inspection was initiated to assess the effect of process parameters on surface finish. Cost effective experimental trials combining speed, feed and depth of cut were formulated using Taguchi L9 orthogonal array. The significant factor influencing surface topography was analyzed using analysis of variance (ANOVA) tool. The examination divulges that the surface roughness was found to be maximum at the lower levels of process meters in the milling process on mild steel material. The ANOVA depicts the process parameter which is greatly contributing to the surface texture.
