Resumo: | The use and costs of solid wood products are directly linked to the quality of the feedstock. One example is the furniture market, the better the surface quality of the wood is, the greater its commercial value is. Knowing the behavior of wood during the machining process is an important parameter to characterize and give specific uses for each species. Thus, the aim of this study was to evaluate the surface quality of wood from Toona ciliata M. Roemer var. australis clones, its potential uses after the machining process and to define, among the evaluated clones, the one with the best surface quality. Thus, thirty-five trees (7 clones x 5 repetitions) were selected from a plantation located in the southern region of Minas Gerais state, from which 1m long logs were removed (0.3 to 1.3 m from the base), and later unfolding on boards. Drying took place in the shade and outdoors, until equilibrium humidity was reached. The machining process (planer and thicknessing) of the boards took place at the forward speeds of 6 m.min-1 and 30 m.min-1. The evaluations of the surface quality took place visually, according to the ASTM D-1666 (2011) standard and by the surface roughness test. Among the seven clones studied, the number 1 presented higher surface quality in machining and, in general, with the increase in the forward speed, there was a reduction in surface quality. |

O mercado moveleiro é exemplo disso, pois quanto melhor a qualidade superficial da madeira, maior será seu valor comercial. Conhecer o comportamento da madeira durante o processo de usinagem é um importante parâmetro para caracterizar e dar usos específicos para cada espécie. Assim, o objetivo do presente estudo foi avaliar a qualidade da superfície da madeira de clones de Toona ciliata M. Roemer var. australis, seus potenciais usos após o processo de usinagem e definir, entre os clones avaliados, o de melhor qualidade superficial. Para isso, foram selecionadas trinta e cinco árvores (7 clones x 5 repetições) de um plantio localizado na região sul de Minas Gerais, das quais retirou-se toras de 1m de comprimento (0,3 a1,3 m a partir da base), e posteriormente desdobrando-se em tábuas. A secagem ocorreu nas condições ambientais de sombra e ao ar livre, até atingir a umidade de equilíbrio. O processo de usinagem (plaina e desengrosso) das tábuas ocorreu nas velocidades de avanço de 6 m.min-1 e 30 m.min-1. As avaliações da qualidade da superfície ocorreram de forma visual, conforme a norma ASTM D-1666 (2011) e pelo ensaio de rugosidade da superfície. Constatou-se que, dentre os sete clones estudados, o de número 1 apresentou maior qualidade de superfície na usinagem e, de modo geral, com o aumento da velocidade de avanço, houve redução da qualidade da superfície.Universidade Federal de Santa Maria2021-09-08T17:47:37Z2021-09-08T17:47:37Z2020-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCRUZ, T.
