Numerical and experimental investigation of cutting temperature in turning with a self-propelled rotary tool

Abstract

This study focuses on the analysis of temperature distribution in a self-propelled rotary insert for dry turning of SKD11 steel both experimentally and numerically using ABAQUS solver. The simulation results showed that the tool temperature increased with increasing the cutting speed, feed rate, and depth of cut, and the self-propelled rotary tool exhibited a considerably lower temperature than that of the one with a fixed cutting edge. The simulation results were experimentally validated by capturing the steady temperature field in the cutting zone with an IR camera. Thanks to the continuous introduction of a fresh part of the cutting edge into the shear region of the self-propelled rotary tool, both simulated and experimental results revealed a large reduction in the tool temperature of more than 170oC at various cutting conditions.
