“…The surface roughness of heat-treated beech machined by milling was slightly higher than that of untreated wood (Ispas et al, 2016). Hacibektasoglu et al (2017) revealed that heat-treating beech (Fagus sylvatica L.) for 1 h and 2 h had a negligible effect on the processing roughness after planing, measured by Rk.…”

The main objective of this study is to determine the effect of heat treatment on the machiningproperties of solid wood material and determine the optimum cutting parameters to obtain surfaces with minimum surface roughness. In line with this goal, Siberian pine (Pinus sibirica) wood species, widely used in the woodworking and furniture industry, was chosen as the experimental material. The heat-treated (at a temperature of 190 °C for 2 hours) and untreated samples were machined using two different cutters (carbide upcut milling cutter and carbide compression milling cutter) with 5 mm diameter at 1000, 1500 and 2000 mm/min feeds, 8000, 12000, 16000 rpm spindle speed, 50, 75 and 100 % stepover on the CNC machine. Surface roughness values (Ra and Rz) were measured to evaluate the obtained surfaces according to ISO 468 (2009), ISO 3274 (2005), and ISO 4287 (1997) using a contact profilometer. When the data was evaluated in general, the lowest roughness value for Ra occurred in upcut milling cutter, with 50% stepover, 12000 rpm, 1000 mm/min feed on untreated solid wood material. The highest roughness value for Ra occurred in a compression milling cutter, with 100 % stepover, 16000 rpm, 2000 mm/min feed on heat-treated solid wood material. It has been observed that the feed is the most critical parameter affecting the surface roughness.

“…Various authors often provide either parameter Ra (Škaljić et al 2009;Budakçı et al 2013;Sofuoǧlu and Kurtoğlu 2015;Vanco et al 2016;Koleda et al 2019;Rajko et al 2021) or Rz (Malkoçoğlu 2007;Aguilera et al 2016), or both of them jointly as indicators of surface quality (Pinkowski et al 2018). In some publications, to ensure a more extensive analysis of tested surface parameters, Ra and Rz are supplemented with parameter Rt (Davim et al 2009;Sogutlu 2010;Pinkowski et al 2016) as well as other additional parameters (Kilic et al 2006;Ispas et al 2016;Gurau et al 2017;Hacibektasoglu et al 2017). For each analyzed case a total of 5 roughness measurements were taken parallel to the direction of feed during machining.…”

The aim of the conducted experiments was to determine the effect of selected machining parameters on power consumption and surface quality obtained during the milling of beech wood using a computerized numerical control woodworking machine. Surface roughness was tested using the contact roughness measurement method, while roughness parameters Ra and Rz were recorded and cutting energy was determined. Tests were conducted for two variants of cutting speed (7.5 and 15 m·s-1) as well as three variants of chip thickness (0.10, 0.06, and 0.02 mm); additionally, the tests examined different cross-sections of wood. It was found that greater chip thickness and feed speed caused an increase in surface roughness and cutting power. In turn, cutting speed had no effect on surface roughness, whereas its increase resulted in increased cutting power. Surface roughness at the radial and tangential cross-sections was comparable, while it was greater at the transverse cross-section. It was also found that cutting power was lowest at the radial cross-section, while it was greater at the tangential and the greatest at the transverse cross-section.

“…Unlike physical and mechanical properties, which are described very extensively in the literature, there is a lack of studies focused on the technological properties of heat-treated wood. However, changes in the mechanical and physical properties are reflected in the machining of thermally modified wood [ 17 ]. As the density of the thermally modified wood decreases, the cutting force is lowered during machining [ 18 , 19 ], which is also reflected in the reduction in energy consumption [ 20 ].…”

Interaction between Thermal Modification Temperature of Spruce Wood and the Cutting and Fracture Parameters

et al. 2021

This work examines the effect of thermal modification temperatures in the production of thermally modified wood on the cutting and fracture parameters when cutting heat-treated spruce wood by a circular sawblade machine. The samples were thermally modified at 160, 180, 200, and 220 °C. One sample was unmodified and was used as a reference sample. On the basis of the performed experiments, the fracture parameters (fracture toughness and shear yield strength) were calculated for the axial–perpendicular direction of cutting. In comparison with the theoretical assumptions, the influence of temperature on the cutting and fracture parameters was confirmed. Thermally treated wood is characterized by increased fragility and susceptibility to crack formation, as well as reduced density, bending strength, and shear strength. These properties significantly affect the size of the cutting force and feed force, as well as the fracture parameters. As the temperature increases, the values of these parameters decrease. The mentioned material characteristics could be useful for the optimization of the cutting process, as well as for the issue of energy consumption during the machining of heat-treated wood.
