Resumo: | The wood of Coffea arabica L. is considered a a residue of the coffee industry and is widely used as a source of energy. Few studies have shown other destinations such as the manufacture of small objects and furniture with rustic design. The objective of this work was to find the best fit in cutting speed during machining planer trowel the wood of Coffea arabica, taking into consideration the quality of the machined surface. The wood from the Coffea arabica came from an 15 years planting, spacing 3 x 2 m, of the municipality of Machado / MG. The tree was pruned, unfolded and flattened, in order for getting cut-proof of 30 mm thick, with variables length and width. The machining tests were performed at the Laboratory of Wood Machining (DCF / UFLA), varying the cutting speed in plane trowel. The qualification of the machined surface was performed by the feed per tooth (fz), visual analysis (ASTM D 1666-87) and roughness Ra and Rz. It was used a completely randomized design with 30 repetitions. We conducted the analysis of variance test and the average of Scott-Knott, at 5% significance level. It was calculated the percentage of marks obtained for the feed per tooth. The results showed that the quality of machined surface with cutting speeds of 19 and 21 m∙s-1 and forward speed of 6 m∙min-1 were satisfactory with small surveys of fiber and low values of feed per tooth ( fz) and roughness Ra and Rz. |
