TīmeklisChropowatość powierzchni jest to niezgodność lub odchyłka od założonego na rysunku profilu. W odróżnieniu od falistości powierzchni, chropowatość powierzchni mierzona jest na niewielkich odcinkach. Opisuje się ją poprzez 2 podstawowe parametry: Ra oraz Rz. Ra – jest to średnie arytmetyczne odchylenie od linii średniej.
