Abstract
We measured the translational and torsional vibrations of the drill bit in the course of drilling process. The measurements were done by laser Doppler interferometric methods measuring the velocities on the basis of the Doppler effect. An LDV (Laser Doppler Vibrometer) device measured the translational vibrations, and then an LTV device measured the torsional vibrations (angular velocity changes) of the drill bit during drilling. Time series and frequency spectra were analysed in some periods of the metal cutting process. We identified translational vibration frequency groups around 100 Hz, above 1000 Hz and above 12 kHz. Meanwhile the typical torsional vibration frequencies were around 4400 Hz and 5600 Hz. We also observed the free oscillation of the drill at 480 Hz (in the pulling out phase), and some pseudo-oscillations at the higher harmonics of the rotational frequency.
