In order to clarify the effects of the oxygen content in the atmosphere on tool wear, high speed face milling tests were carried out on plain carbon steel S45C and stainless steel SUS 304 with carbide, cermet and ceramic tools. Cutting tests were conducted in the sealed chamber of which the atmosphere was changeable. In the case of milling S 45 C in the low oxygen content atmosphere, the crater wear reduced drastically and oxide layers were observed on the rake face of the tested tools. A logarithmic relation was found between the crater wear and the concentration of oxygen in the atmosphere. It was also found that the thermal cracks on the rake face reduced with the decrease of the oxygen content in the atmosphere. In the case of SUS 304,the crater wear was not influenced by the oxygen content, but the chipping wear seem-ed to be suppressed by the decrease of the oxygen content.
