Abstract

At the Kielce University of Technology a novel approach to measurements of sphericity has been developed. The approach involves application of traditional radial measuring instrument equipped with a special-purpose fixing unit allowing accurate positioning of measured ball. The new concept required developing of the set of mathematical equations allowing, for example, the calculation of the reference sphere parameters. The paper assumptions of the new concept and the mathematical model of calculation of the reference feature by the radial method with respect to sampling points density. The theoretical analysis is supported by the practical example.
