The coordinates deviation of a CMM (three coordinates measureing machine) is estimated as error vectors within 1 μm of uncertainty, by using 2 laser tracking stations.The error vectors were estimated as the differences between coodinates data of the instrument and estimated positions by the least square method. The calibration or correcting method developed through grasping error vectors at overall working area of an instrument shall give a CMM system with computer to decrease measuring errors. The availability of this method was only verified on the plane coordinates, because laser tracking stations with one rotate axis was used for this experiment. It is easy to extend the plane coordinates to three coordinates if laser tracking stations with two axes for the three coorninates system are used.
