Messsystem zur automatischen Feststellung und Korrektur von Positionsabweichungen von Bauteilen von Maschinen und/oder Geraeten

The measuring system uses a number of sensors (15,16,17,19), each secured to a stationary part of the machine tool and cooperating with a corresponding machine tool component, for determining the relative positions of the latter components. The sensors are directly or indirectly associated with a measuring beam (14), e.g. via a secondary measuring beam (18) at a given angle to the first measuring beam, each of the sensor mountings and the fixing between the measuring beams provided by a thermally neutral transmission system (20). USE - For evaluating and correcting position of adjustable components within a machine tool. ADVANTAGE - Prevents thermal expansion measuring errors
