The study assessed the changing of Ra, Rp, Rv and Rz roughness parameters of the sanded beech surface (Fagus sylvatica L.) as a function of different grit sizes and different measurement direction. The milled samples were ground with a belt sander BS-75 E-set from Festool with belt grit P60, P100 and P150. The sanding belts were Rubin 2 from Festool. Roughness was evaluated using a Keyence VHX-7000 digital microscope. The evaluation length of the roughness measurement was 12.5 mm (λc = 2.5 mm and λs = 8 mm). The R-parameters were measured in accordance with the latest standards ISO 21920 (2022) in the direction parallel to the grain, and in the direction perpendicular to the grain (profile). The paper proves the theoretical assumptions about the reduction of R-parameter values. The measurements showed that the sanded surface was less rough in the direction perpendicular to the grain at P150 sanding belt grit and in the grain direction at P100 grit.

W pracy oceniono zmianę parametrów chropowatości Ra, Rp, Rv i Rz szlifowanej powierzchni buka (Fagus sylvatica L.) w funkcji różnej wielkości ziarna i kierunku pomiaru. Zmielone próbki szlifowano szlifierką taśmową BS-75 E-set firmy Festool o ziarnistościach taśmowych P60, P100 i P150. Taśmy szlifierskie to Rubin 2 firmy Festool. Chropowatość oceniano przy użyciu mikroskopu cyfrowego Keyence VHX-7000. Długość ewaluacyjna pomiaru chropowatości wynosiła 12,5 mm (λc = 2,5 mm i λs = 8 mm). Parametry R zostały zmierzone zgodnie z najnowszymi normami ISO 21920 (2022) w kierunku równoległym do włókien oraz w kierunku prostopadłym do włókien (profil). Artykuł potwierdza teoretyczne założenia dotyczące redukcji wartości parametru R. Pomiary wykazały, że szlifowana powierzchnia była mniej chropowata w kierunku prostopadłym do włókien przy ziarnistości taśmy ściernej P150 oraz w kierunku włókien przy ziarnistości P100.
