The surface roughness model is developed in terms of main cutting parameters such as cutting speed, feed rate, depth of cut and tool nose radius, using a full-factorial design approach. Machining tests were carried out in turning AISI 4140 steels with CVD-coated carbide cutting tools under different conditions. Moreover, analysis of variance is used to examine the impact of machining parameters on surface roughness. It is shown that the feed rate was found to be main influencing factor on the surface roughness, followed by tool’s nose radius. However, it decreased with decreasing the feed rate while it increased with decreasing the nose radius. The other parameters remained a stable. Furthermore, the interaction of feed rate/tool’s nose radius was found to be statistically significant on the surface finish because their p-values are smaller than 5%.
