Coating materials which were synthesized on the P30 carbide substrate are titanium carbonitride titanium nitride chromium nitride and titanium nitride aluminum nitride. Cutting tests were performed at cutting speeds of 30 40 50 and 60 m s depth of cut of 1 mm and feed of 0.05 mm rev. Wear parallel force and noise level were measured at every specified cutting length. The purpose was to discriminate various stages of wear of the coated carbide tools by the features extracted from parallel force and noise level. The results of the study show that both the parallel force and noise level generated by the tools tested were observed to increase linearly with increasing the tools wear and would be good parameters for monitoring the tool wear. The parallel force and the noise level of the cutting tools also increased with increasing the cutting speeds for every specified cutting length. The parallel force became more sensitive than the noise level for monitoring the tool wear when the cutting speed was increased. coated carbide tool parallel force noise level wood-chip cement board cutting speed Résumé - Estimation de l usure d outils carbures revêtus à partir de paramètres extraits de l analyse du bruit et des efforts de coupe.
