In-situ characterization of tool temperatures using in-tool integrated thermoresistive thin-film sensors

Abstract Metal cutting is characterized by high temperatures at the tool-workpiece interface. Although valuable information could be provided temperature values, their direct measurement still presents a challenge due to contact pressure and inaccessibility of process kinematic. In this research work, current state thin-film sensors for measuring on chip-tool interface has been analyzed with focus phenomena: thermoelectricity thermoresistivity. Thin-film placed tools in or close tool-chip area are expected obtain accurate expense short lifetime. New insights into manufacturing, design calibration presented, new concept three-point thermoresistive sensor proposed. During orthogonal tests workpiece deformations were measured through high-speed imaging sensors. order validate distribution edge, Finite Element simulations carried out. Finally, potential using integrated in-situ characterization investigated statement its limitations applications given.
