$a Measurement of the roughness of the sanded surface of beech wood with the profile measurement software of the keyence VHX-7000 microscope $f Lukáš Adamčík, Richard Kminiak, Jarmila Schmidtová 215 $c Graf., obr., tab. 320 $a Lit. 330 $a Sanding is the most important way of reducing unevenness and preparing the surface for the final treatment. To optimize sanding, it is necessary to quantify the effect of abrasive grit size on surface roughness. The paper deals with the methodology of measuring the surface roughness parameter Ra of beech wood (Fagus sylvatica L.) using a Keyence VHX-7000 digital microscope. After milling, the samples were sanded with abrasives with grit size from P40 to P150, using an eccentric sander. Roughness was evaluated in two directions according to ISO 21920 (2022) standards. Using a two-factor analysis of variance the positive effect of grit size on roughness was proven. It improved on average by 38% in the direction perpendicular to the grain and by 20% parallel to the grain. The theoretical knowledge about equalizing the unevenness of the surface by sanding and reducing the difference between the roughness in two directions is proven in the paper. 463 -1
