From the results of the previous paper, it has been confirmed that the atmosphere is important as well as mechanical or thermal shock in intermittent cutting. In order to clarify the effects of oxygen content in the atmosphere on thermal cracks, high speed face milling tests were carried out in the sealed chamber reported before. The main results obtained were as follows : (1) The thermal cracks on the rake face were suppressed with the decrease of oxygen content in the atmosphere. (2) A logarithmic relation was found between the number of cutting cycles which the thermal crack was observed and the concentration of oxygen in the atmosphere. (3) The effects of the atmosphere on thermal cracks decreased with the increase of cutting speed.
