Abstract : In this study, the effect of machining parameters on surface roughness is investigated during CNC end milling process of Al6061 – T6 Alloy by Taguchi’s method. The work material was machined with uncoated carbide tool and TiAlN coated carbide tool and comparative analysis have made between coated and uncoated tool for identifying the better surface finish. ANOVA analyses were carried out to identify the significant factors affecting surface roughness, and the optimal cutting combination was determined by seeking the best surface roughness and signal-to-noise ratio. Finally, confirmation tests verified that the Taguchi design was successful in optimizing milling parameters for surface roughness.
