    摘要： A positioning control apparatus for accurately positioning a tool and workpiece and for reducing the vibration related to positioning. The system comprises a machining table fitted with a workpiece and designed to be movable on a bed. A first detector detects the acceleration of the machining table in a moving direction, and a second detector detects the acceleration in the moving direction of a tool fitted to a column that also is coupled with the bed. The outputs of the first and second detectors are used to suppress the relative vibration of the workpiece fitted to the machining table and the tool fitted to the column in the moving direction.
