Correction of Systematic Errors in Piezoelectric Cutting Force Measurement

Systematic measurement errors in piezoelectric cutting force measurements are researched within this thesis. The errors originate from the seismic mass, which is mounted upon the transducer. On the one hand, the seismic mass reduces the bandwidth of the measurement system. On the other hand, the seismic mass leads to superimposed inertial forces, when the seismic mass is subjected to motion during cutting force measurement. Both effects are modelled and correction methods were researched, which are capable to correct these systematic measurement errors in hard real-time.
