Effect of drying temperature on surface roughness of oak (Quercus petraea ssp. iberica (Steven ex Bieb) Krassiln) Veneer

This paper reports the effect of various drying temperatures on the surface roughness (SR) characteristics of veneer samples. Three SR parameters [average roughness (Ra), average maximum height of the profile (Rz), and root mean square roughness (Rq)] were measured on sliced veneer obtained from Oak logs (Quercus petraea ssp. iberica (Steven ex Bieb) Krassiln). The sliced veneers were dried at 100, 115 and 130 °C drying temperatures for 2 min. Roughness measurements were taken from the surface of the samples in across the grain orientation of the veneer. The results showed that the effect of drying temperatures used in practice is statistically significant on SR of the sliced veneers.
