U radu su prikazani rezultati uticaja termičke modifikacije na snagu rezanja potrebnu za glodanje drveta. Eksperiment je izveden za različite temperature tretmana (170°C, 190°C i 210°C) i različite tehnološke parametre obrade (pomak i dubina glodanja). Snage rezanja tokom glodanja merene su na četiri grupe uzoraka bukovog drveta dimenzija 35×16×400 mm, posebno za srčevinu i beljiku. Za obrađene uzorke testirana su mehanička i fizička svojstva drveta: savojna čvrstoća, modul elastičnosti pri savijanju, poprečna i bočna tvrdoća i gustina u prosušenom stanju vlažnosti. U ispitivanju je korišćen merni uređaj za merenje, praćenje i prikazivanje snage rezanja, razvijen u Centru za mašine i uređaje na Šumarskom fakultetu u Beogradu. Rezultati ukazuju na postojanje razlika u snagama potrebnim za obradu termički obrađenog drveta u odnosu na netretirano drvo. Utvrđeno je da sa povećanjem temperature tretmana potrebne snage rezanja opadaju.
The paper presents results of influence of thermal modification on cutting power required for milling wood processing. The experiment was conducted for the different treatment temperatures (170°C, 190°C and 210°C) and different technological parameters of processing (feed and cutting depth). Cutting powers during milling were measured on four groups of beech wood samples, dimensions 35×16×400 mm, separately for heartwood and sapwood. The following mechanical and physical properties of the processed samples were tested: bending properties (modulus of rupture and modulus of elasticity), cross-sectional and tangential hardness, and air-dry density. The measuring device used for measuring, monitoring and displaying cutting power was developed at the Wood Machining Centre at the Faculty of Forestry in Belgrade. The results point out the differences in the powers required for processing heat-treated wood compared to untreated wood. The analysis shows that with the increase in treatment tempe...rature, the required cutting powers decrease.
