Milling is one of the most important metal cutting processes. If we can measure the cutting force of milling process in real time, we will be able to make cutting process optimum, prevent tool breakage. But especially when we use an end mill with small diameter, it is very difficult to measure the cutting force in real time because of its small cutting force. In this paper, we developed a tool holder with torque sensing function in it by using a magnet coupling with magnetoresistance sensors. Especially, we developed the technique which can compensate error by using analog circuit. Thus we confinned that it can improve an accuracy of torque measurement.
