“…and Dipteryx odorata (Teles, 2014). Such results suggest that the roughness is a variable characteristic among the species, because it is influenced, among other factors, by the anatomical composition, wood density and by machining processes and parameters, as seen in other works (Lopes, Nolasco, Tomazello Filho and Dias, 2014).…”

The objective of this investigation was to evaluate the roughness, wettability and the surface color of Ficus sp. genus before and after the process of manual sanding and application of a finishing product (stain). The roughness and color were determined before and after the sanding process and after applying the stain using Surftest SJ 400 Mitutoyo and ColorEye XTH spectrophotometer. The wettability was evaluated by measuring the contact angle between the water drop and the surface of the veneers, using a goniometer Krüss DSA30. The roughness of the veneers, subjected to 180, 240, and 320 sandpaper, decreased after the sanding process and remarkably after stain application. The contact angle was over 90° for all treated samples. Regarding the colorimetry, there was a decrease in L* average values after sanding. After applying the stain, there was a change in color of the wood, from grayish-white to yellow-olive.

“…Os valores médios de rugosidade Ra nos diferentes parâmetros de usinagem foram próximos do trabalho realizado pelos autores Lopes et al (2014), que avaliaram a superfície da madeira de E. grandis, E. urophylla e E. dunnii aos 18 anos utilizando velocidade de avanço de 15 m*min -1 e rotação de 3450 min -1 , obtendo a rugosidade Ra de 2,27.…”

O objetivo do trabalho foi gerar conhecimento científico que contribua para a melhor eficiência dos parâmetros envolvidos na usinagem a partir de diferentes métodos para qualificação da superfície usinada e avaliar o uso das espécies de Eucalyptus e Corymbia na produção de piso, como também, analisar a relação da densidade e desvio da grã com a rugosidade da madeira. Foram utilizadas as espécies E. dunnii, E. urophylla, E. grandis, C. citriodora e C. maculata, todas com 37 anos. Para o ensaio de usinagem foram utilizados corpos de prova com dimensões de 800 x 100 x 25 mm, velocidades de avanço de 15 e 30 m*min-1 e velocidade de corte da ferramenta de 18 e 25 m*s-1. Foi realizada a qualificação da superfície usinada por meio do avanço por dente, análise visual e parâmetros de rugosidade, sendo realizado também a relação da densidade e desvio da grã com a rugosidade da madeira. As madeiras de todas as espécies foram classificadas como ruim e muito ruim pela qualificação visual, os valores de avanço por dente foram acima dos indicados para pisos de madeira. Os menores valores dos parâmetros de rugosidade foram obtidos nas madeiras com maior densidade e menor desvio da grã. Ao utilizar os diferentes métodos de qualificação de superfícies nas madeiras de Eucalyptus e Corymbia, observou-se baixo potencial para utilizar essas madeiras em pisos. No entanto, é necessário que sejam realizados outros estudos com diferentes velocidades de avanço e de corte para verificar a possibilidade de melhoria nas qualidades superficiais dessas madeiras.

“…Several studies indicate that surface roughness is strongly influenced by wood density. In general, higher density woods have a lower surface roughness value (Amorim et al, 2013;Lopes, et al, 2014;Teles;Costa;Souza, 2016). However, Zhong, Ng and Hiziroglu (2018) studying the surface roughness of Pinus (Pinus resinosa), Red oak (Quercus rubra) and Nyatoh (Palaquim sp.)…”

In the Amazon, the sustainable use of wood is associated with technological research that indicates industrial use. Surface roughness of wood is an important criterion for assessing tool condition, machining performance and product quality. The objective of this study was to evaluate the surface roughness of five Amazonian woods used in the manufacture of EGP (Edge Glued Panels).The woods Angelim pedra, Angelim vermelho, Breu vermelho, Murici and Piãozinho, obtained from managed areas of the Amazon, were used in the manufacture of EGP panels. Surface treatments were performed with 120 and 180 grit sandpaper. Surface ripples (roughness) were measured using a digital roughness meter with needle (n = 180 readings). Physical and mechanical tests were performed on both wood and EGP samples, to verify the possible relationship between these properties and roughness. EGP Piãozinho presented better surface quality, which consists of lower roughness (lower surface wave height), while EGP Angelim pedra presented uneven surfaces. Surface quality was satisfactory when 120 grain sandpaper was applied to most products. The results showed a highly significant effect of roughness such as the physical-mechanical properties. The highlight of the study is the wood and EGP Piãozinho, because in all the tests, it always presented the best performances.
