The aim of the static calibration of the dynamometer is to obtain the matrix for evaluating cutting forces through the output voltage of the piezoelectric cells and charge amplifiers. In the same time, it is worth to evaluate the linearity of the dependencies between applied forces and output voltage and also the reproducibility of the assessed forces.The aim of this report is to present the following necessary steps in order to have a high reliable dynamometer:1. Dismounting of the dynamometer;2. Verification of the dynamometer components;3. Alignment of the piezoelectric cells;4. Preloading of the piezoelectric cells;5. Mounting of the dynamometer;6. Calibration of the dynamometer;7. Data analysis;8. Uncertainty budget of the calibration.
