Abstract

Along with fast development of industry and manufacturing techniques, also the coordinate metrology, which is closely linked with requirements of modern manufacturing systems, is developing. The increase in products quality requirements provides a new tasks for manufacturers of measuring instruments. Time of measurement, as well as requirements for its accuracy generate development of the new solutions in coordinate metrology systems, as well as the continuous improvement of existing ones. Undoubtedly, one of the newest and fastest growing solutions are Coordinate Measuring Arms. <BR />The paper presents a new conceptual approach for a calibration of Coordinate Measuring Arms. The novelty of the method is usage of the LaserTracer System as a standard of length according to ISO 10360-2:2009 and elimination of operator influence on measurement result by replacing him by an Industrial Robot. In this method, the robot is programed to repeatedly move the coordinate measuring arm. The stylus of coordinate measuring arm is replaced by reflector, which works with a LaserTracer system. The LaserTracer system is tracking the reflector and measuring the distance to it. The precise LaserTracer system is used here as a standard of length and gives a base for arm accuracy assessment.
