摘要：

In order to realize high-speed and high-precision machining, the enhancement of the motion accuracy of NC machine tools is required. It is effective to minimize the friction forces imposed on drive systems to enhance the motion accuracy. From this viewpoint, we developed a high precision machining center using linear motors and hydrostatic guideways for its drive system. The disturbance forces on the developed machining center are measured to evaluate the fundamental motion characteristics. Contouring error trajectories in high-speed circular motions of small radii are also measured for the evaluation of roundness.
