Measuring the surface roughness values of european hop-horn beam (Ostrya carpinifolia scop.) wood

In this study, the samples obtained from European hop-horn beam (Ostrya carpinifolia Scop.) wood has been subject to cutting with circular saw, planing with a thickness machine and sanding with a caliber sanding machine (with no: 80 sand). After the specimens were processed in the machines in radial and tangential surfaces, their surface roughness values (Ra, Ry, Rz) have been determined in accordance with the ISO 4288 standard. According to the statistical results, the lowest roughness values have been achieved with the thickness machine. Similarly, the roughness values of tangentially cut surfaces have been found to be lower than the radially cut surfaces. © 2018 Statny Drevarsky Vyskumny Ustav. All rights reserved
