Intelligent material is widely used in the semi-active vibration control systems due to its the advantages as simple control, responding quickly, easy control of characteristic parameters, low power consumption and roubst. In this paper, the damping device for machine tool based on intelligent materials so called magneto-rheological fluid was developed to reduce vibration in a cuboid parts. The theory showed that the best damping effect is getting about optimal damping ratio 0.26. Thus, a fuzzy control system with magneto-rheological fluid for the damping device for machine tool was developed. The test results showed that under cutting conditions without the magneto-rheological damper the fuzzy control system can effectively reduce the amplitude and suppress the vibration of the machine tool.
