ABSTRACT:
A device and method for active vibration damping of an object which comprises a beam with two free ends comprises a vibration sensor, a control circuit, and an actuator. The sensor is located near the first end of the beam and the actuator is located near the second end of the beam. The control circuit converts input signals from said vibration sensor into control signals for controlling the actuator. The damping device is particularly useful where it forms part of a precision coordinate measuring machine which has a beam of varying length. In this instance, the sensor is located on a sliding spindle of the measuring machine.
