In this study, a three-component dynamometer design, construction and its calibration were carried out. The dynamometer system consisted of three 20 kN high capacity single point load cells, three isolated strain gauge input modules, a terminal board, an analogue-to-digital card and a software for recording and analyzing the data. The load cells were mounted in three different planes vertical to each other. These load cells were loaded up to 10 kN in various steps from unloaded condition. The output strains obtained as the results of the loads were recorded and these files were introduced to the software. The system records four data each of which consists of the average of 256 data block per second. By using the dynamometer, the forces occurring during clamping of workpiece and during cutting were monitored on the PC screen and their magnitudes were accurately transferred to the PC. Besides, the dynamometer was used on larger sized workpieces successfully.
