“…Some of the other sources are described in references [5][6][7][8], but so far, neither the results of research nor an explanation of how temperature changes influence surface topography parameters are published. There were only publications in which the authors considered thermal expansion of a device, its particular elements, and a workpiece as the factors influencing the measurements [9][10][11].…”

Abstract. The paper presents an analysis of influence of ambient temperature changes on the values of parameters in topography measurements with the use of different profilometry techniques. In order to check this, a series of measurements was performed. Two multiprofilometry instruments were used -a contact profilometer, further equipped with an interferometric transducer, and an optical one with a confocal probe. Measurements were performed on first-class flat interferometric glass and on an A-type roughness standard -under different conditions, with simultaneous registration of differences in ambient temperature values. These values were either intentionally changed or the temperature variations were the result of air conditioning control. The performed research showed that -despite the asperities on the surface being really small -there is a relationship between changes of temperature and the results obtained from the measured surface, which in some cases can be seriously distorted.

“…Efekty termiczne można polepszyć odpowiednią kombinacją materiałów o różnych współczynnikach rozszerzalności cieplnej. W [1] stosowano układ składają-cy się z drutu stalowego nawiniętego na pręt inwarowy. Wzrost temperatury zmniejszał naprężenia obwodowe wywoływane przez stal na inwarze i w efekcie zmniejszał długość pręta (oczywiście w określonym zakresie).…”

Experimental research of selected sources of errors in profile measurements of surface asperities

Przedstawiono wyniki badań doświadczalnych związanych z wybranymi błędami w profilowych pomiarach nierówności powierzchni. Omówiono wpływ synchronizacji ścieżek pomiarowych, błędy skręcenia i możliwości przyrządów pomiarowych oraz zakłócenia pochodzące z otoczenia -zarówno wysoko-, jak i niskoczęstotliwościowe. Pokazano, że powtarzalność punktu początkowego i nawet powolne zmiany temperatury w otoczeniu przyrządu pomiarowego mają istotny wpływ na wiarygodność pomiarów. SŁOWA KLUCZOWE: pomiary profilowe, topografia powierzchniIn the paper experimental results of research regarding selected errors in profile measurements of surface asperities were presented. Influence of synchronization of measurement tracks, errors coming from rotation and possibilities of measurement devices as well as interference from conditions in both: high and low frequencies were discussed. It was shown that repeatability of the first point and even slow temperature changes around a measurement device have a great influence on fidelity of results.
