This paper highlights tool wear mechanisms in the machining of heat resistance alloys including nickel-based Inconel 718 alloy which is one of the most popular material in the aircraft industry. Special attention was paid to the notch wear which develops on the flank face due to high temperature oxidation of the cutting tool material at temperature of about 8000C. The experimental procedure includes the diffusion couple methods and tool wear tests which assess the degradation of the deposited coating. The obtained results were supported by SEM images of the flank face periphery and EDS analysis performed in the regions of intensive oxidation. Some conclusions and ongoing research on the investigation of the oxidation phenomenon of cutting tool materials are outlined.
