The amplification of forced vibration in plunge-cut cylindrical grinding is analyzed theoretically and experimentally. In machining works of a certain size range, the forced vibration coming from the gear pump in a specific grinding machine is found to increase gradually or rapidly after start of grinding. This paper discusses a general mechanism of the vibration amplification as experienced with the case and methods of suppression are explained. The effectivity in suppression is confirmed experimentally.
