“…Some researchers have concentrated on examining the manufacturing parameters of MDF, which is more homogenous than solid wood (Aguilera et al 2000;Davim et al 2009;Sütçü and Karagöz 2012). The relation between the sound pressure level and surface roughness in milling using CNC machines has been examined in manufacturing using beech wood (Iskra and Tanaka 2005).…”

The aim of this study was to evaluate the effect of CNC routing, using different parameters with the Taguchi experimental design, on the surface quality of various wooden (pine, spruce, and beech) edge-glued panels (EGP). The study evaluated five processing parameters: cutting direction, cutting depth, cutting width, feed rate, and spindle rotation speed, and their effects on surface roughness on pine, spruce, and beech EGP. Based on the results of statistical analysis of the burr surface roughness values, the mentioned parameters affected panels at varying levels. It was seen that the parameters were only responsible for ~34% (R z ) of the roughness on the surface of pine EGP, ~49% (R z ) of spruce EGP, and ~27% (R q ) of beech EGP. Statistically important parameters were as follows: cutting direction for pine, cutting depth (tip diameter) and feed rate for spruce, and cutting direction and feed rate for beech.

“…The surface coatings are closely linked with the surface roughness by the fact that the roughness plays an important role in the performance and stability of the specific coating applied to the wood. Difference in surface roughness at changed cutting conditions for MDF have been reported by Kilic et al (2006), Davim et al (2009), Davim et al (2008), Hiziroglu and Kosonkorn (2006), Dippon et al (2000), Aguilera et al (2000), Lin et al (2006), Akbulut and Ayrilmis (2006) and Engin et al (2000), where surface quality problems are related to the change of cutting conditions and also with raw material characteristics. For example, in a study on MDF milling, Davim et al (2009) evaluate the effect of cutting speed and feed rate on the surface roughness, concluding that the increase of spindle speed or the decrease of the feed rate, provide best results of quality.…”

“…For example, in a study on MDF milling, Davim et al (2009) evaluate the effect of cutting speed and feed rate on the surface roughness, concluding that the increase of spindle speed or the decrease of the feed rate, provide best results of quality. Also, studies carried out by Aguilera et al (2000), Aguilera et al (1999) indicate the existing relation between the chip thickness and surface roughness, being this directly proportional, where a smooth surface is obtained with a small chip thickness, although with a high energy expense; and with a decrease of tool life.…”

This research takes the option of using sound pressure signals to monitor the resulting surface roughness from rip sawing process of medium density fibreboards samples. Different cutting conditions were evaluated, namely cutting speed and feed, giving as a variable the mean chip thickness, being also assessed the effect of the climb cutting and conventional cutting mode. The main results lead to conclude that the sound pressure was closely related to the variation of the mean chip thickness giving adequate levels of correlation with the surface roughness. A positive, linear relationship was observed between feed rate and surface roughness, as well as for sound pressure. The best surface quality was achieved when climb cutting mode was applied. Then, the measurement of sound pressure results is a useful method to monitor MDF cut process, being possible to predict the surface roughness, as well as the effect of the change of cutting conditions. Keywords: Sound pressure, circular saw, MDF, surface roughness. RESUMENEsta investigación considera la opción de usar las señales de presión de sonido para monitorear la rugosidad superficial resultante del proceso de corte longitudinal con sierra circular de paneles de densidad media. Se evaluaron diferentes condiciones de corte, en particular la velocidad de corte y de avance, entregándose como variable el espesor medio de viruta, también se estudió el efecto del modo de corte convencional o concordante. Los principales resultados indican que la presión de sonido se correlacionó muy bien tanto con la variación del espesor medio de viruta como con la rugosidad superficial. Una relación lineal positiva se observó tanto entre la tasa de alimentación y la rugosidad, como también con la presión de sonido. La mejor calidad de superficie se obtuvo con el modo de corte en concordancia. Los resultados de la medición de presión de sonido son un método útil para controlar el proceso de corte de MDF, siendo posible predecir la rugosidad superficial y el efecto del cambio de las condiciones del proceso. Palabras clave: Presión de sonido, sierra circular, MDF, rugosidad superficial.

Medium Density fiberboard (MDF) panels are economic alternative to engineering materials because of their superior advantages in furniture industry. The degree of surface roughness of the MDF panel plays an important role, since any surface irregularities will reduce the final quality of the product. Design of experiments has been used to study the effects of the drilling parameters such as speed, feedrate, and drill diameter (input data's) used on the prediction of surface roughness (output response) on drilling MDF composite. The present work describes the development of mathematical models to predict the two surface roughness parameters namely average roughness(Ra),and mean peak to valley height (Rz) which were used to determine quantative surface characteristics of the panels. Experiments were performed under different drilling conditions of spindle speed, feed rate and drill diameter.Residual plots were constructed to analyze the variation between the experimental values and model values. Analysis of Variance (ANOVA) was employed to identify the level of importance in drilling parameters on their performance characteristics.The effect of these parameters on surface roughness has been investigated using Box-Behnken experimental design. Response contours were constructed for determining the optimum drilling condition for the required surface roughness. The developed model establishes a correlation between speed, feed rate and drill diameter that influence the surface roughness in a MDF panel. Analysis of variance (ANOVA) is employed to study the surface roughness characteristics in drilling operation of MDF board. The analysis of variance showed high coefficient of determination (R 2 ) value of 0.99 and 0.9842 for Ra and Rz respectively, thus ensuring a satisfactory adjustment of the second order regression model with experimental data. The verification experiment is carried out to check the validity of the developed model. The surface roughness of the predicted model during the confirmatory test has 2.06% and 2.631% error for Ra and Rz respectively, which is well within the tolerable limits.
