This paper investigates the parameters affecting the Material Removal Rate (MRR) & Roughness of surfaces produced in the shaping process for the material 6061 Aluminium. Design of experiments was conducted for the analysis of the influence of the shaping parameters such as cutting speed, feed rate and depth of cut on the surface roughness. The results of the machining experiments for Al 6061 were used to characterise the main factors affecting surface roughness by the Analysis of Variance (ANOVA) method. Feed rate founds to be a most influencing parameter for the surface roughness in the shaping process whereas depth of cut is found to be significantly affecting the MRR.
