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, su rface quality, and chip formation mechanics. To understand the exact t emperature rise in the tool-chip interface has been recognized as an i mportant study in achieving the best cutting performance. For the abov e reason, an inverse estimation of the heating history on the rake fac e of cutting tool is presented in this paper. The first stage of the a nalysis is to solve a heat transfer model of cutting tool with three-d imensional boundary element method. This is a direct heat transfer pro blem. Furthermore, the inverse heat transfer technique of sequential e stimation 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 te mperature contours on the tool-chip interface.
