Abstract: Surface roughness produced on the machined component is one of the key attribute of machining process. In this work the effect of various turning process parameters on surface roughness produced on Al6061 (as cast condition) is investigated. Also the effect of using coolant on surface roughness while turning is also determined. It is observed increase in cutting speed by 39.29% resulted in decrease of surface roughness by 31.44%. Increase in feed rate and depth of cut leads to increase in surface roughness. Quantitative analysis of surface roughness obtained in machining with coolant and without coolant is also presented.
