Cutting temperature and forces are two dominant parameters that influence finish quality and tool life in machining. This paper undertakes the evaluation of these two factors in relation to machining by a self-propelled rotary tool, an efficient cutter recently reported to be superior in cutting some new materials. Temperature analysis is based on a model of a heat source movind cyclically along the cutting edge. Both analytical and experimental rtsults indicate that the rotating motion of the cutting edge transfers heat away from the cutting zone with the result being a reduced cutting temperature. Temperature of the cutting edge drops to the neighborhood of the ambient value after it passes the cutting zone. Cutting forces of the rotary tool are found to be smaller, especially the radial thrust component, which is 30-40 % lower, than those of the fixed circular tool.
