A Practical Algorithm of Evaluating Roundness Error by Minimum Circumscribed Circle

Peng Xiao

Abstract

Aiming at application and evaluating algorithm of minimum circumscribed circle for roundness error,this paper introduces a searching method of minimum circumscribed circle center and it achieves fast and accurate evaluation of roundness error.The evaluating theory and mothod of minimum circumscribed circle for roundness error are expounded.The corresponding program is developed,and the minimum circumscribed circle evaluating of roundness error by three coordinates measuring machine in the cartesian coordinates is realized.
