Abstract

Wood products used in the furniture industry need to have wood work machine surfaces quality optimized and patronized. There are some classification methods to determine the wood quality, including visual inspection, determination of the advance per tooth (fz), rugosimeter and laser or just touching. After the wood classification it is determined the usage of the different wood qualities. The empiricism of the quality parameters in the indication of uses is not always ideal. This study determined the quality of surfaces of Eucalyptus flat wood and defined appropriate uses for the different quality classes obtained. It had been worked machine different Eucalyptus samples by planer with speed of advance of 3,6,15 and 30 m*min-1. To classify the wood, the determination of the advance per tooth (calculated fz and measured fz) and the visual qualification (ASTMD 1666-87, 1995) were used. Later the wood usage according to quality was determined. The percentage of good samples decreased as the speed advance increased: reaching 92%, 69%, 0% and 0% for advance speed of 3,6,15 and 30 m*min-1 respectively. Samples prepared at the speed of 3 and 6 m*min- 1 were used to fabricate furniture, cabinet frame and thresholds. About 54%of samples prepared at the speed of 15 m*min-1 were used for railing, lambris, structural panels and flooring. About 46% and 100% of samples prepared at the speed of 15 and 30 m*min-1, respectively, were used to fabricate dividers, trusses, fences and, or, exterior gates.
