“…The average values of surface roughness are given in Table 2. Among all roughness parameters considered in this work, Rk was the most representative for processing, with no errors introduced by wood anatomy (Gurau et al 2005). The highest value of 20.8 µm was found for alder samples sanded with 180 applied after 80 grit size.…”

“…The sampling length and measuring resolution were set with respect to the recommendations given in the literature for wood surfaces as 2.5 mm and 5 µm, respectively (Gurau et al 2005). The equipment software automatically applied a Gaussian data filter and the roughness profile was obtained (Fig.…”

“…Therefore, the roughness parameters of the Abott-curve defined by ISO 13565-2 (1996) were also used in order to evaluate the sanded surfaces. The core roughness (Rk) and the fuzzy grain roughness (Rpk) were taken into consideration because Rk is the most representative indicator of processing roughness (Gurau et al 2005). However, as long as the anatomical roughness was not removed, the anatomical roughness parameter (Rvk) was excluded from the surface quality evaluation.…”

The objective of this study was to evaluate the adhesion strength and glossiness of black alder wood (Alnus glutinosa Gaertn. L.) coated with water-borne and UV varnishes by two application systems. Prior to coating, the samples were prepared by sanding with four combinations of grit size sandpapers, 180 being the final grit. The surface quality of the specimens was measured with a white light profilometer. Any increase in grit size gradually reduced surface roughness, which further influenced the overall coating performance of the samples. UV varnish applied by roller presented higher adhesion strength and gloss as compared to spraying. The specimens varnished with a water-borne finish by spraying exhibited a better adherence to the substrate than those of UV varnished samples by the same method and provided glossiness at 60° geometry in the same range. These results are valuable for the furniture manufacturing industry for generating a better use and efficiency of secondary wood resources in order to achieve value-added products.

“…However, if anatomy is not removed from the measured profile, the Rk parameter is a good approximation of the processing roughness (Westkämper and Riegel 1993;Gurau 2004;Sharif and Tan 2011). This parameter (Rk) measures the core roughness of a profile, and it should be sensitive to wood processing and surface heat treatment.…”

“…In order to visualize the results, the core roughness (processing roughness) was separated from the other surface irregularities by upper and respectively lower thresholds with a method described by Gurau et al (2005) to allow visual comparisons between milling conditions and wood treatment.…”

Several previous studies have investigated the effects of heat treatment on the chemical composition, along with the physical and mechanical properties, of wood from various species. However, the effects of these property changes upon the machining properties and surface quality of machined wood have been studied much less. The main goal of this work was to investigate the comparative cutting power consumption during milling and the resulting surface roughness of heat-treated and untreated beech wood (Fagus sylvatica L.). Several cutting regimes were tested by combining different values of rotation speed, feed speed, and cutting depth. The cutting power and the processing roughness were assessed and compared. The results clearly showed that the cutting power involved in the milling of heat-treated beech wood was up to 50% lower than that of untreated wood, but the processing roughness was slightly higher.
