In this study, Al-12Si ingot alloy was melted in an electric resistance furnace and then poured into metal moulds through traditional casting method. Optimum machining conditions is aimed to determine by investigating the effects of cutting parameters on surface roughness. For this purpose, The machining tests were carried out through single point turning operations at without coolan on CNC turning at cutting speeds (250, 350 and 450 m/min), feed rates (0.1 0.15 and 0.2 mm/rev) (0.5 1 and1.5 mm) deep of cut was defined at three different levels and the experiment was designed with Taguchi's L9 vertical array. Variance analysis (Anova) was performed to determine the effect of cutting parameters on the surface roughness. According to the obtained analysis results, it has been determined that the most efficient parametric advancement cutting speed rate is 90.55%
on surface roughness.
