“…Hendarto et al (2006) determined the effect of various methods of the surface Ra evaluation and the changes in values between methods depending on the filtration used and partial difference of certain methods. The conclusions of the research by Budakçı et al (2013) indicated that the laser method is more suitable for determining the surface quality than the contact method. Table 8 shows an evaluation of the effect of factors on the surface Ra measured by the contactless method using Duncan's test.…”

The mean arithmetic deviation of the roughness profile was investigated during cylindrical milling of the board edges. The machined materials were a medium-density fiberboard, medium-density fiberboard with single-sided lamination, and edge-glued spruce panel. Contactless and contact profilometers were used to measure the roughness. Both methods were evaluated and compared. Tungsten carbide blades with three different compositions and treatments were used. The effect of the cutting speed (20 m/s, 30 m/s, 40 m/s, and 60 m/s) and feed rate (4 m/min, 8 m/min, and 11 m/min) on the surface roughness was also monitored. The results of this study compared two different methods for determining the surface roughness. The measurements were more accurate with a contactless profilometer, but the price is higher than that of the contact method. The operation was also more complicated, and the measurement itself took longer with a contactless profilometer. The evaluation of individual surface quality variables was faster with a contact device. The best results in terms of the surface quality were achieved by lowering the feed rate and increasing the cutting speed.

“…A capacidade para quantificar e controlar a rugosidade da superfície, que varia em larga escala, como resultado das diferenças metodológicas no processamento da madeira utilizando ferramentas ou máquinas, é muito importante em várias aplicações (Yildiz, 2002). Cada objeto tem uma superfície composta por picos e vales em miniatura e a distribuição dimensional e de área desses picos e vales afeta as propriedades da superfície (Budakçi et al, 2013).…”

RESUMOO objetivo do trabalho foi avaliar a rugosidade e a molhabilidade da superfície de lâminas de madeira de curupixá (Micropholis venulosa) antes e após o processo de lixamento manual e aplicação de seladora. A rugosidade foi estimada usando-se um rugosímetro; para avaliar a molhabilidade utilizou-se um goniômetro. A rugosidade das lâminas submetidas a lixas de diferentes números de grão abrasivo (180 e 240) diferiu em relação àquelas não lixadas. No entanto, a rugosidade das lâminas lixadas com números de grão abrasivo 180 e 240 não apresentaram diferença significativa entre si, mesmo após a aplicação da seladora. Quanto ao ângulo de contato, o menor valor foi encontrado para as lâminas lixadas com o número de grão abrasivo 240 após a aplicação de seladora. Assim, a aplicação de lixa combinada com produto de acabamento melhora a qualidade de superfície das lâminas, implicando em melhor qualidade do produto acabado.Palavras-chave: rugosidade, ângulo de contato, lâminas de madeira. Surface Evaluation of Micropholis venulosa Decorativeveneers ABSTRACTThis study aimed to evaluate the roughness and the wettability of Curupixá (Micropholis venulosa) veneers surface before and after manual sanding and application of sealer. The roughness was estimated using a profilometer and the wettability with a goniometer. The roughness of the veneers subjected to different levels of abrasive sandpapering (180 and 240) differed from those not sanded. However, the roughness of sanded veneer with abrasive sandpaper number 180 and 240 showed no significant difference among themselves, even after the sealer application. As for the contact angle, the lowest value was found for the veneers sanded with the number of abrasive sandpaper 240 after applying sealer. Thus, sanding along with finish product improved the surface quality of the veneers, resulting in a better quality of the finished product.

“…Knowing the cutting power, it is then easy to determine the cutting force, which is understood as the force that has to be exerted on the machining tool in order to overcome the resistance of the wood and perform the chip-forming process (Budakçı et al 2013;Novak et al (2011);Lesko 2004) (Eq. 2)…”

This paper deals with an analysis of the energy efficiency of the milling of thermally modified and unmodified beech wood, taking into consideration the angular geometry of the cutting tool (milling cutter). The analysis was made using the METREL Power Q plus MI2392 device to measure the cutting power of the machine during milling with predetermined technical and technological cutter settings. The results were compared with respect to electricity savings in industrial production. The electrical power of the milling cutter, when machining thermally modified wood, was 5% less on average compared with the machining of unmodified wood under identical technological conditions.
