In this study, the effects of different cutting tool coating materials on surface roughness of work piece were investigated as well as the cutting parameters. For this purpose, AISI 1040 steel was machined by two different cemented carbide cutting tools coated with Al2O3 by PVD (Physical Vapour Deposition) and triple coated (TiN on uppermost) by CVD (Chemical Vapour Deposition) and no coolant was used in turning operations. In these tests, five different cutting speed values (58, 83, 116, 163, 225 m/min) and two different feed rate values (0.24, 0.32 mm/rev) were used with constant depth of cut (2.5mm). According to test results the minimum average surface roughness was obtained with the cutting tool having triple coating on uppermost TiN. 14% improvement was observed in average surface roughness by increasing the feed rate 33% and 114% improvement was obtained by increasing the cutting speed 388%.
