The article presents the results of simulation studies aimed at verifying the usefulness of the concept of calculating kinematic straightness errors from angular errors. Based on the calculations of a flexible machine tool, no relationship was found between the two types of errors. This clearly shows that straightness errors and angular errors of machine tools should be treated as independent of each other.

W artykule przedstawiono wyniki badań symulacyjnych, celem zweryfikowania przydatności opracowanej koncepcji przeliczania charakterystyk błędów kinematycznych prostoliniowości na podstawie charakterystyki błędów kątowych. Analiza wyników obliczeń odkształcalnego stołu obrabiarki nie potwierdziła ścisłej zależności pomiędzy tymi błędami. Jest to podstawą do stwierdzenia konieczności traktowania błędów prostoliniowości i błędów kątowych obrabiarek jako niezależnych.
