$a The effect of thermal modification of beech wood on the quality of milled surface $f Lukáš Adamčík, Richard Kminiak, Adrián Banski 215 $c Graf., obr., tab. 320 $a Lit. 330 $a Steamed wood is currently increasingly used in the woodworking industry. Wood treated in this way eliminates growth stresses, offers higher resistance to weathering and partially better machinability resulting from its more increased fragility. The article quantifies the influence of the degree of thermal treatment on the quality of the created surface on beech wood (Fagus sylvatica L.). The samples were created by milling technology with a shank positive spiral milling cutter on a CNC machining center at specified values of cut depth and feed rate. The basic task of the experiment is to verify that thermally modified wood shows a higher surface quality compared to thermally untreated wood, which the authors defined through the values of the arithmetical mean deviation of the roughness profile – Ra and the arithmetical mean deviation of the waviness profile – Wa. Both parameters were measured using a laser profilometer LPM-4. The evaluated samples partially pointed to the assumption of the literature research into a decrease in roughness and waviness (due to the effect of thermal modification) and, thus also to the assumption of improved surface quality. In the case of roughness, there was an increase in surface quality at a steaming temperature of 105 °C (by 9.78 %) and 125 °C (by 22.80 %). In the case of waviness, an increased surface quality was found at a wood steaming temperature of 105 °C (by 43.12 %). In both cases, already higher temperatures of thermal modification caused a re-increase in roughness and waviness. The stated results mean a specific progress in understanding the role of thermal modification by steaming, as it can, in addition to improved physical, mechanical and chemical properties, fundamentally influence the future quality of the surface of the semi-finished or finished product. 463 -1
