Abstract
This paper deals with the cutting temperature on turning with a self-propelled rotary cutting tool. The measurement of the cutting temperature was carried out by tool-work thermocouple. The characteristics of the rotary cutting tool was compared with that of the conventional cutting tool. In addition, the cutting temperature was discussed by means of cutting energy which was estimated by cutting force and mechanism of chip formation and so forth.
The results obtained are as follows.
1) The cutting temperature on turning with the rotary cutting tool is smaller than that with the conventional cutting tool, and the discrepancy varies in the inclination angle of tool.
2) The difference of temperature between the rotary cutting tool and the tool with the fixed edge depends on the heat generation of the region of tool-chip interface rather than that of the shear region.
