USINAGEM DA MADEIRA DE CINCO ESPÉCIES NATIVAS BRASILEIRAS

This study was to compare the behavior of five native Brazilian species: angelim (Andira anthelmia), a canela (Anila firmula), cedro (Cedrela fissilis), ipe amarelo (Tabebuia alba) e a muiracatiara (Astronium lecointein) through testing machining. It was made ten samples for each kind of dimensions following the U.S. ASTM D 1666-87. Still determined the apparent density of the wood (g.cm-3) based on the NBR 7190 in order to establish possible relations For machining tests, all species behave well with relation to the sanding and drilling for peg no significant differences between the grades obtained. However, the ipe submitted the worst result for the planing test and cedro due to its smaller apparent density obtained the worst result front of drilling tests. With respect to turning test, species of ipe and canela were rated as the best among the tested species. Overall, it was concluded that the species showed potentials of uses in furniture, frames and general finishing occasions.
