Milling Machine Vibration

This paper presents a method of micro-vibration control of milling machine heads by use of a vibration absorber.The principle used in this paper is different from that of usual absorbers.An auto-tuning vibration absorber is presented in which the absorber creates anti-resonance state.When the anti-resonance is used, the damping has to be significantly small, so it is difficult to suppress.
