In a turning process, surface roughness depends on machining process parameters. The aim in this work is to improve the quality of the machined surface of the by controlling the main input parameters of the turning process for aluminum and steel materials. The effect of the machining parameters on surface roughness was studied using the orthogonal L9 Taguchi method. Four process parameters chosen were the length of the specimen (L), diameter of the specimen (D), feed rate (F), and depth of cut (T). The optimization method was performed using the signal to calculate noise ratio (S / N) for the changing response of all experiments. The results were analyzed using the analysis of variance (ANOVA). The main conclusion of this work is that F and T are the most important factors and can influence the machined surface quality in terms of surface roughness, whereas the other factors are insignificant. The minimum surface roughness for aluminum is 1.03 μm and 5.02 μm for steel specimens, which were obtained using a more suitable set of parameters with values of T 0.5 mm, F 0.5 RPM., L1000 mm, and D 40 mm.
