Machining Effect on the Surface Roughness of Eucalyptus benthamii Wood

ABSTRACT

The objective of this research was to evaluate the effect of planing and sanding on the surface roughness of Eucalyptus benthamii Maiden et Cambage wood. Surface roughness measurements were carried out using a Surftest SJ - 301 Profilometer. Surface images obtained by a trinocular stereo microscope were also analyzed. The E. benthamii surface roughness was not affected by the machining method (planing or sanding). However, it was possible to observe through the images that the sanded surface presented fibrillation and scratches, while the planed surface showed open vessel cells.
