Surface roughness is one of the key measures in manufacturing that describes machined surface integrity. In this research work, the effect of silicon morphology on surface roughness when turning Al-11%Si-1.8%Cu alloy and Sr-containing alloys was investigated. The experiments are carried out under oblique dry cutting conditions using a PVD TIN-coated insert at three cutting speeds of 70, 130 and 250 m/min, feed rates of 0.05, 0.1, 0.15 mm/rev, and 0.05 mm constant depth of cut. The result released that surface roughness decreased with adding 0.04 wt.% Sr to casting. The surface roughness values reduce with cutting speed increment from 70 m/min to 250 m/min. Also, the surface finish deteriorated with increase in feed rate from 0.5 mm/rev to 0.15 mm/rev.
