The objective of this paper is to develop a taguchi optimization method for low surface roughness in terms of process parameters when turning the EN-353 steel on conventional lathe machine. Considering the process parameters as Depth of cut, Feed, Spindle Speed, Rake Angle & Pressurized Coolant Jet, a series of turning experiments were performed to measure surface roughness data. Taguchi orthogonal arrays, signal-to-noise(S/N) ratio, and analysis of variance (ANOVA) are used to find the optimal levels and the effect of the process parameters on surface roughness. Confirmation experiment with the optimal levels of process parameters was carried out in order to demonstrate the effectiveness of the taguchi method. It can be concluded that Taguchi method is very suitable in solving the surface quality problem of turned work pieces.
