Abstract
An apparatus provided with wedge-shaped elements is proposed for the precision positioning of objectsto be measured or machined. A wedge-shaped translational bodyis carried by two bearing wedges. In accordance with the invention the wedges can be independently translated in the x direction. The body is translated in the z direction by moving the bearing wedges over an equal distance but in opposite directions. The body is translated in the y direction by moving the bearing wedges over an equal distance in the same direction. The mutually moving parts of the apparatus are carried by means of fluid bearings. A high precision is thus obtained, because fewer errors due to non-infinite stiffnesses and error motions are accumulated. A laser measuring apparatusis used for measuring and adjusting the position of the object carrier
