Abstract: The objective of this investigation was to determine the influence of machining parameters on the surface roughness of AISI 1050 steel and grey cast iron work pieces. It was observed that the surface roughness decreases with the increase in cutting speed. On increasing the feed for AISI 1050 steel, initially the surface roughness decreased up to 0.12 mm/rev feed and thereafter it increased, but for grey cast iron it increased with feed for all cutting conditions. The surface roughness was not affected significantly by tool separation distance. Compared to single tool turning process, the double tool turning produced much better surface finish. As a consequence, it is possible to reduce the cost of machining by suitably targeting the process parameters. An approximate cost analysis has been done to support this claim.
