Study on the Correction of Cutting Force Measurement with Table Dynamometer

This paper studies the correction of cutting force measurement with table dynamometer. The cutting force measurement tests and impact tests are carried out to obtain measured cutting forces and measured transfer function between the measured cutting forces and applied forces, respectively. According to the analysis of these experimental data, it is found that the distorted measured cutting forces are caused by the significant errors of cutting forces at two times and three times tooth passing frequency. Using a Kalman filter technique, the distorted measured cutting forces are corrected. The results of cutting force correction are very well and verify the theory that in frequency domain, cutting forces mainly concentrate on tooth passing frequency.
