A Simulation on Influence of Cooling at Rake Face to Tool Temperature

Abstract

Abstract In this paper, heat balance equation at the tool is derived and modified. The equation covered heat generated at tool-chip interface and dissipation via rake face and flank face. Based on heat balance equation derived, heat removal from the tool can be improved by reducing rake face length exposed to ambient air. A cooling source from water is introduced at a fraction of exposed rake face with high heat transfer coefficient. Finite element study conducted shows tool temperature closed to cutting edge is reduced by 23% by increasing length of water cooling at rake face. In addition, increasing area of water cooling shows significant impact on tool temperature when tool temperature decent by 31% compared to without cooling from water. The presence of cooling source at a fraction of exposed rake face has remarkable effect on tool temperature.
