CONCEPT OF REFERENCE MEASUREMENTS OF CYLINDRICITY PROFILES OF MACHINE PARTS

Stanislaw Adamczak, Dariusz Janecki, Krzysztof Stepien

Abstract

Products with cylindrical surfaces are manufactured in many (e.g. paper, chemical, steel, heating or shipping) industries. It is required that regular estimations of cylindricity profiles be made during the production process. The reference methods can be used for measurement of cylindricity. The cylindricity deviation includes the roundness deviation in different cross-sections of an object, the relative change of its diameter and the noncentricity of profiles in relation to the nominal axis of the object. The reference measurement systems applied nowadays enable measurement of roundness profiles in relation to fixed points of support in different cross-sections of the measured object. Furthermore, it is possible to evaluate the relative difference of the diameters. However, in traditional reference measurement systems there is no possibility of measurement of the non-concentricity of profiles. That is why appropriate reference systems for measurement of cylindricity have had to be developed.
