Determination of temperature distributions on the rake face of cutting tools using a remote method

Cutting temperature is a major factor in controlling the tool wear, surface quality, and chip formation mechanics. To understand the exact temperature rise in the tool-chip interface has been recognized as an important study in achieving the best cutting performance. For the above reason, an inverse estimation of the heating history on the rake face of cutting tool is presented in this paper. The first stage of the analysis is to solve a heat transfer model of cutting tool with three-dimensional boundary element method. This is a direct heat transfer problem. Furthermore, the inverse heat transfer technique of sequential estimation is employed to simulate the time histories of heat fluxes at the rake face based on the measured temperature responses on the tool measuring point. The present model can be used not only to determine the part of heat flux conducting into the cutting tool but also the temperature contours on the tool-chip interface.
