This paper aims to study the effects of cutting condition to the power consumption and surface quality in tuning process on mild steel S50C. The machine was used in this study is CNC turning and carbide cutting tool. The optimize process parameters by means utility concept and Taguchi technique applied to identify the machinability and energy efficiency. The three types of process parameters with five different levels including, cutting speed, feed rate, and depth of cut have been used in this work. The selection of these parameters was based on literature review, and tool manufacturing recommendations. The Taguchi orthogonal array L25(53) have been used for conducting the experiments. The results shown that most significant factor for power consumption is depth of cut (60.58%) followed by feed rate (30.27%) and cutting speed (4.36%). For surface roughness, the most significant factor is feed rate (98.49%) followed by depth of cut (0.99%), and cutting speed (0.02%). Nevertheless, the minimum power consumption of machine condition is in contrast to the surface roughness quality. Therefore, this technique can be applied for production planning to control the product quality and machining cost.
