Abstract

In this study, the relation between tool flank temperature and surface roughness in turning of sintered steel was examined. The tool flank temperatures of CBN and ceramic tools were measured by a two-color pyrometer with an optical fiber. In dry turning, the CBN tool in turning of sintered steel showed a higher temperature by 50°C－120°C compared with that of carbon steel. The higher thermal conductivity cutting tool showed lower tool flank temperature. The temperature mitigation effect of coolant was remarkable in turning with the higher thermal conductivity cutting tool. The surface roughness decreased with tool flank temperature. At the same tool flank temperature, smaller surface roughness was obtained in wet turning compared with dry turning.
