Positioning technology supporting the development of the ultraprecision machine tool is summarized. For the basic understanding of positioning technology, dynamics of the positioning mechanism and tribology of the guideway are explained. Then, positioning system using hydrostatic lubrication widely used in the ultraprecision machine tools is described, where the positioning resolution of the system is 1nm (10⁻⁹m). Finally, it is shown that the positioning with 10pm (10⁻¹¹m) resolution is realized by using the active control of the aerostatic guigeway.
