Streszczenie: W artykule przedstawiono analizę aktualnego stanu wiedzy o pomiarach odchyłek kulistości oraz założenia opracowanej koncepcji pomiaru kulistości metodą kombinowaną, umożliwiającą pomiar zarysów okrągłości przedmiotu w kilku przekrojach, tzw. południkowych, a następnie pomiar zarysu okrągłości tzw. równikowego. Do takich pomiarów mogą być wykorzystane promieniowe przyrządy pomiarowe wyposażone w odpowiednie zespoły mocujące przedmiot.
Abstract: In hitherto practice sphericity measurement methods have been based on measurement of roundness profiles in a few selected sections of the sphere and that is why they cannot give accurate quantitative and qualitative information on the investigated surface. Therefore producers of spherical machine parts (roll bearing or automotive industry) expect development of the concept that would allow full graphical presentation of the measured surface and its reliable evaluation by selected parameters. The method that could meet these expectations is so-called combined method. This method allows measurement of roundness profiles of the workpiece to be set on the measuring table in a few meridianal sections and then measurement of the roundness profile in one parallel section. Such measurement can be performed by radius change measuring devices equipped with appropriate fixing units. The paper presents the current state-of-the-art on the measurements of sphericity deviations and fundamentals of the developed concept.
