description A positioning control apparatus and a machine tool which are capable of improving positioning accuracy without impairing the acceleration performance of a feed device and therefore performing a more highly accurate positioning are provided. A positioning control apparatus has a moving body, a feed device having a guide mechanism for guiding the moving body in the direction of its feed axis and a drive mechanism for moving the moving body, a structural body 2 supporting the feed device and a controller 20 for controlling a moving position of the moving body with respect to a reference position on a machine tool by controlling the operation of the drive mechanism, and further has a calculating section 11, 28 calculating displacement of the feed device in the feed-axis direction with respect to the reference position caused by displacement of the structural body and a compensating section 27 receiving the displacement data measured by the calculating section 11, 28 and adding modification data for eliminating the displacement to a control signal in the controller 20.
