The principle of plane-to-planc perpendicularity measuring with coordinate measuring machine (CMM) is described and the main factors that influence the measuring precision are ana-lyzed. The minimum condition method is adopted to eliminate the fitting error of the datum plane. In order to diminish the length error of the object plane, the tactics of measuring some part of the plane and then scale to the whole plane is employed. With large quantity of measuring experiments on flat plates, the most appropriate number of points in measuring a plane is determined to reduce the sam-piing error.
