The purpose of this study is to develop the new machine bed support mechanism which can reduce the vibration generated in high speed tracking motion. In order to achieve the purpose, frequency response and motion trajectory are measured on the machine supported by the proposed machine bed support which has sliding surface, and compared with the results measured on the machine supported by the conventional one. A mathematical model that can represent the influence of the machine support characteristic is also developed. The simulated frequency responses are compared with the measured ones. As the results from the experiments and simulations, it is confirmed that the vibration generated in high speed tracking motion can be reduced by the proposed machine bed support which has sliding surface.
