This research aims to clarify the cutting phenomenon at the high-speed interrupted cutting while paying attention to the cutting temperature. Carbon steel S45C was machined in the face milling within the range in cutting speed 269-2089m/min. The cutting temperatures and the tool wear characteristics, when the high-speed interrupted cutting was done, were investigated from the viewpoints of the cutting speed and the real cutting time in one rotation. The cutting temperature was measured by using the tool-work thermocouple method. As the results, in low cutting speed, the wear progress rate of the interrupted cutting was higher than that of the continuous cutting, but the wear progress rate of the interrupted cutting lowered oppositely in the high cutting speed range. And, the cutting temperature had the maximum peak at a certain cutting speed for the increase of the cutting speed under the cutting condition that the cutting time shortened very much, and the maximum peak shifted to the low cutting speed side as the width of the work material became small. It was understood that there was a possibility of decreasing the cutting temperature in high-speed interrupted cutting.
