Determination of Surface Roughness Based on the Sanding Parameters of Oriental Beech Wood

Abstract

This study demonstrated the strength of a theoretical model founded on the Box-Behnken experimental design method to determine the surface roughness (Ra parameter) of solid Oriental beech (Fagus orientalis Lipsky) wood. The working parameters (sanding belt grit size of 60 to 100, feeding speed of 4 m/min to 10 m/min, and sanding cutting depth of 0.1 mm to 0.3 mm) of a wide belt sanding machine were determined. The Ra of the samples was experimentally described so that the experimental results were also remodeled with the Box-Behnken method to find the optimum parameters for the lowest Ra. An adjusted correlation factor of 93.6% for the Ra confirmed the compatibility between the experimental and theoretical findings. The high correlation (strength) allowed for a more detailed discussion of the effect of the working parameters on the Ra. The theoretical approach showed that the grit size factor had the largest effect on the Ra compared with the other factors. The optimum parameters were found to be a grit size of 100, feed speed of 4 m/min, and sanding depth of 0.1 mm for a minimum Ra for Oriental beech wood. The experimental data supported these parameters.

Effect of Thermo-Vibro-Mechanic® Densification Process on the Gloss and Hardness Values of Some Wood Materials

“…With the TVM densification process, the gloss increased by 372% on the radial surface and by 442% on the tangential surface compared to the control samples. In the literature, it is stated that the tangential section forms a smoother surface than the radial section (Sönmez et al 2002;Budakçı et al 2011;İlçe 2018). Thus, this study is compatible with the literature.…”

Comparison of Surface Roughness of Beech Wood after Sanding with an Eccentric and Belt Sander

“…The purpose of coarser grits in practice is to remove significant surface irregularities, while smaller grits are involved in the resulting smoothing of the surface, the removal of protruding fibers and the overall preparation of the surface for surface treatment. Currently, most authors deal with the sanding of wood and wood materials with a belt sander [14][15][16][17][18]. Because of this reason, there is a lack of information about the quality of the created surface after sanding with other technologies: for example, an eccentric sander.…”

Engineering calculations and numerical modeling of composite adhesive plywood panels

“…Similarly, the possibility of producing veneer for glued veneer panels from ash and red pine [8], hardwood [9], fast-growing poplar and eucalyptus [10], modified poplar veneer [11], and also obtained by combining various wood veneers [12] was studied.…”
