The major needs in machining are high material removal rate, good work surface finish and low tool wear. These objectives can be achieved by reducing tool wear using proper cooling system of the tool during machining. The work aims to seek conditions in which dry cutting is satisfactory compared with the,flood of fluid usually used. The cutting tool used in this research is CVD coated carbide TiC+Al2O3+TiN insert (ISO P25). The type of inserts is DNMG 150608. During the experiments flank wear, cutting force and surface roughness value were measured throughout the tool life. The results have been compared with dry and wet-cooled turning. The results of the present work indicate substantial reduction in tool wear, which enhanced the tool life; this may be mainly attributed to reduction in cutting zone temperature and favorable change in the chip-tool interaction.
