In this paper, a feed drive under the influence of base dynamics is investigated in an existing horizontal machining center. By using sensitivity analysis on the servo simulation model with base dynamics, vibration at positioning are analyzed. As a result, it is found that the vibration at positioning can be reduced by the change of installation condition of the machine.
