Abstract : The cutting temperature was measured in turning aluminum at cutting speeds of 50-33 m/sec. The cutting tool was of VK8 hard alloy and the readings were recorded with an N-102 oscillograph. It was found that the cutting temperature increases nonuniformly with an increase in cutting speed. At 50-100 m/sec, the temperature increase is not so great, and at 120-170 m/sec there is almost no increase. It is assumed that, with an increase in the tangential component of the cutting force at high speeds, friction on the leading edge of the cutting tool is increased, thereby increasing the cutting temperature.
