The fundamental aim of this paper is to assess various methods of surface topography slope calculations. Computer generated and measured 2-D profiles and 3-D surface topographies of random and asymmetric ordinate distributions were analysed. The paper examines the use of various differential formulae for the calculation of surface slope. The effect of measurement errors on random profile slope was analysed. Dependence among slope and other parameters, relation between average and rms slope as the measure of profile asymmetry were studied. Variation of profile slope was examined. Prediction of surface slope after 2 processes was performed. The errors of obtaining surface slope based on profile slopes in orthogonal directions were analysed based on computer generated and real surface topographies. The deviation between profile slopes in two orthogonal direction as the measure of anisotropy of honed cylinder surfaces was examined.

Podstawowyrn celem pracy jest ocena różnych metod obliczania pochylenia powierzchni. Przedmiotem analizy były generowane komputerowo oraz mierzone struktury geometryczne powierzchni losowych o różnych kształtach rozkładu rzędnych w układach 2D i 3D. Analizowano przydatność różnych wzorów stosowanych przy obliczaniu pochylenia. Badano wpływ błędów pomiarów na zniekształcenie pochylenia powierzchni losowych; określano wpływ błędu kwantowania, błędu spowodowanego kształtem i wymiarami końcówki pomiarowej, filtracji cyfrowej, zakłóceń wysokoczęstotliwościowych, obecności pojedynczych rys głębokich. Analizowano zależności między wartościami pochylenia i innych parametrów, analizowano też zmienność pochylenia powierzchni losowych. Badano stosunek średniego arytmetycznego i średniego kwadratowego pochylenia jako parametr określający kształt rozkładu rzędnych. Określono możliwość przewidywania pochylenia powierzchni dwuprocesowej. Określono błędy obliczenia pochylenia powierzchni losowych na podstawie pochyleń w dwóch prostopadłych kierunkach. Określono przydatność stosunku wartości pochyleń w dwóch prostopadłych kierunkach jako potencjalnego parametru opisującego stopień anizotropii powierzchni cylindrów po gładzeniu.
