We developed a wireless multifunctional tool holder system equipped with a thermocouple in the end mill to monitor the tool internal temperature. We compared the temperature measured by high performance infrared thermographic imagery with that measured by a wireless tool holder system when end milling the stainless steel under dry coolant conditions. We confirmed that the tool internal temperature measured by the wireless tool holder agrees with one calculated by FEM model based on infrared thermographic imagery. As a result, we demonstrated that the developed method with a wireless system is effective to estimate the tool temperature in end-milling processes.
