Resumo: http://dx.doi.org/10.5902/1980509817472The objective of this study was to study the machined surface quality of Eucalyptus grandis wood submitted to heat treatment. The machining operations realized on the boards obtained from the processing of six trees were: planing, thicknessing, tear in horizontal drilling, drilling, drilling hinge and sanding. 208 boards of 125 x 25 x 500 mm were selected, with 104 untreated and 104 heat-treated boards at maximum temperature of 190ºC. The evaluation of the surface was performed according to ASTM D-1666/87 standard. The result showed that the Eucalyptus grandis wood presents a good behavior during the machining tests, obtaining notes 1 and 2 (excellent and good), except for drilling hinge test in the bolt hole and drilling with 12, 8, 6 mm, reaching notes between 2 and 4 (good, regular and bad). The heat treatment reduced the number of defects on the machined samples, except for torn grain in some machining operations.

As operações de usinagens realizadas nas tábuas obtidas a partir do processamento de mecânico de seis árvores foram: desempeno, desengrosso, rasgo na furadeira horizontal, furação, furação para dobradiça e lixamento. Foram selecionadas 208 tábuas de 125 x 25 x 500 mm, sendo 104 não tratadas e 104 tratadas termicamente a uma temperatura final de 190ºC. A avaliação da superfície foi feita de acordo com a norma ASTM D-1666/87. O resultado mostrou que a madeira de Eucalyptus grandis apresenta um bom comportamento durante os testes de usinagem, obtendo notas 1 e 2 (excelente e bom), exceto para os testes de furação para a dobradiça no furo passante e furação com broca de 12, 8 e 6 mm, pois alcançaram notas entre 2 e 4 (bom, regular e ruim). O tratamento térmico diminuiu a quantidade de defeitos nas amostras usinadas, com exceção para o defeito grã arrancada, em algumas operações de usinagem.Universidade Federal de Santa Maria2015-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1747210.5902/1980509817472Ciência Florestal; Vol. 25 No. 1 (2015); 145-152Ciência Florestal; v. 25 n. 1 (2015); 145-1521980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/17472/10494Palermo, Gilmara Pires De MouraLatorraca, João Vicente De FigueiredoCarvalho, Alexandre Monteiro deGarcia, Rosilei Aparecidainfo:eu-repo/semantics/openAccess2017-04-11T18:10:03Zoai:ojs.pkp.sfu.ca:article/17472Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-11T18:10:03Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
