Abstract：The force measuring tool holder system can be used to monitor the axial force and torque changes during the cutting process in real time. In order to ensure the accuracy of the measurement data of the designed force measuring tool holder system, a set of calibration auxiliary devices is developed, a static and dynamic calibration experiment platform is built, and the static and dynamic calibration experiments are completed. The static characteristic indexes such as linearity, repeatability and hysteresis of the force measuring tool holder system are determined by the step-by-step loading and unloading method. The dynamic characteristic indexes such as natural frequency, damping ratio and maximum working frequency of the force measuring tool holder system are obtained by the pulse method.Finally, the drilling and milling experiments are carried out, and the results show that the measurement errors of the system in the axial direction and torque direction are less than 2% compared with the Kistler dynamometer, which means that the system can accurately reflect the changes of axial force and torque in the dynamic cutting process.
