Tool failure modes and wear mechanism of coated carbide tools when drilling Ti-6AI-4V

This paper reports on the performance of TiAlN and Supernitride coated carbide tools when drilling titanium alloy, Ti-6Al-4V. Tool life, tool failure modes and tool wear mechanisms were examined at various cutting speeds of 25, 35, 45 and 55 m/min with a constant feed rate of 0.06 mm/rev. Results sh...
