This paper describes the mechanism of orthogonal cutting at high temperature employing mainly the analysis of mechanism with the transitional deformation range and experimental data for lead, brass, carbon steel and stainless steel. From the experimental results, it was revealed that the sector angle of flow region and inclination of ending boundary line increased with work temperature, and the tendency of the orthogonal cutting mechanism at high temperature was similar to that of increasing rake angle of the tool. In consequence, it was found that the machinability based upon the chip formation at high temperature was better than that at room temperature.
