| Abstract: | The measuring principle of plane-to-plane perpendicularity with a coordinate measuring machine is described,and main factors that influence measuring precision are analyzed.Minimum area method is applied to eliminate datum plane fitting error.In order to diminish the length error of measured plane,the tactics of measuring some part of plane and then scale to the whole plane is employed.Through large quantity of experiments,the most appropriate number of points for measuring plane is determined to reduce sampling error. |
