Iterative Method of Adjusting the Radius of the Spherical Probe of Mobile Coordinate-Measuring Machines When Monitoring a Rotation Surface

An iterative method of probe radius compensation of mobile coordinate-measuring machines when controlling bodies of rotation is examined. The new method minimizes the angle between the normals at the specified point to the nominal and actual profiles as a result of successive approximations. Results...

Summary:An iterative method of probe radius compensation of mobile coordinate-measuring machines when controlling bodies of rotation is examined. The new method minimizes the angle between the normals at the specified point to the nominal and actual profiles as a result of successive approximations. Results of measurement and data handling showed high efficiency of the iterative method by comparison with known methods that are based on the least squares method. The greatest effect on reducing the error of probe radius compensation is reached with a small number of measured points and their non-uniform arrangement on the surface of the component part.
