ABSTRACT
The paper studies the temperature distribution in the tool, chip and workpiece during the orthogonal cutting process. The tool, chip and workpiece have been considered as a single system. The heat generated in the cutting process has been considered as two distributed heat sources, one the heat generated in the primary shear deformation zone due to chip formation, and the other the heat generated in the secondary shear deformation zone as result of chip deformation and sliding friction between the chip and tool. The finite difference method has been taken into account. The temperature distributions in the tool, chip and workpiece as well as the proportions of the heat flowing into the tool, chip and workpiece under several different cutting conditions have been calculated. The temperatures on the surface of the tool and the tool shank were measured under the same cutting conditions by using embedded fine thermocouples and infrared method. It shows the calculated results are reasonable agreement with the experimental data and good agreement with the previously published results.
