Investigation of the relation between tool wear and thermal dissipation on tool flank face

Abstract

The propose of this study is to investigate the relation between tool flank wear and thermal dissipation on tool flank face. Tool flank wear and cutting temperature in dry cutting of Inconel 718 were analyzed. The temperature in the tool was measured by a sensor placed at the bottom face of the tool. The temperature field in the tool was estimated by using the inverse heat conduction method. The results show that there is linear relation between the tool flank wear and the measured temperature at the bottom face of the insert. Based on this result, the temperatures on tool rake face and on tool flank face were estimated. It is confirmed that tool flank wear plays a great role on the temperature rise and thermal dissipation on tool flank face.
