Abstract: In cutting research, the determination of the spatial force system of cutting processes is extremely important. Therefore, the forces generated need to be measured with high precision. In this paper, the development of a special three-component dynamometer system is presented for the measurement of small forces (0100 N) in three directions during fine cutting, with a precision of 0.1 N. The designed dynamometer employs a piezo-electric cell and can easily be mounted on the tool post with only small modifications to the tool holder. The setup was calibrated for sensitivity, static load and range. By using error functions, the relative error in the measurement of force is kept below 1.5%.
