This paper studies the effects of cutting parameters in the tool wear and surface quality (roughness). The tests were carried out on a CNC lathe, using uncoating and coating cemented carbide tool under finish cutting conditions. Microestuctural characterization of tool wear and surface was made using scanning electron microscopy (SEM). The turning of the Ti (6Al-4V) alloy is very difficult due the rapid tool wear. Such behavior result of its low thermal conductivity in addition the high reactivity with the cutting tool. After the machining, the aluminum samples were analyzed with the aim to investigate the mechanisms, which influence the finish of machining surfaces. In the all analyzed samples were observed typical characteristic of machining surfaces, as feed marks, typical deformations of built-up edge (BUE) beyond deposited particles in the machining surface. A typical formation of the side flow mechanism was also observed.
