Abstract
For the ultra-precision machine tools, vibration isolators are used in the machine support to reduce influence of the floor vibration. Particularly, rocking vibrations have influences not only on the tool-work piece displacement but also on the servo drive system. In this research, the location of the vibration isolators for the ultra-precision machine tools is analyzed in conjunction with the vibration induced by machine motion. The measurement of the transfer functions with the hammering was carried out for this purpose. It was found that the four-points-support has better vibration reduction performance to the machine motion than three-points-support in the rocking mode.
