The deviation of circularity estimation of large-scaled details in many cases is a serious metrological problem, which can be solved using a measuring system based on a multistage self-orientating gauge. The purpose of this paper is to study the influence of the gauge parameters on the accuracy of measurement of the circularity deviation and optimization thereof in order to ensure the maximum correspondence between the real and the measured profile. The accuracy of the re-creation of individual and group of harmonic components of the profile is examined. Analytical and experimental research results are provided.
