Kúdela, Jozef, 1954- The influence of milling and sanding on wood surface morphology / Jozef Kúdela, Leoš Mrenica, Ľubomír Javorek. -- Obr., tab. -- Lit. - The influence of milling and sanding on surface morphology of beech and spruce wood is investigated in the paper . Wood morphology was assessed through roughness and waviness parameters. The experimental results showed that the two wood surface machining techniques studied differed in their impacts on the wood roughness and waviness . Lower roughness was obtained by m illing, with the milling parameters (rotation rate, specimen feed speed) not influencing the roughness significantly. The roughness of sanded surfaces was noticeably higher, with the prominent influence of the sanding grit size. In all cases, the roughness was significantly higher perpendicular to grain. T he roughness - related results showed that the differences between beech and spruce wood were noticeably reduced by the mechanical treatment . Despite this fact, the impact of wood species was confirmed. The porous character of wood is the cause of the higher roughness of the wood external surface. This implies that wood surface roughness can be smoothed by an appropriate mechanical treatment, but an absolutely smooth surface cannot be acquired.
