20.500.12556/RUL-158767 Določitev optimalnih parametrov laserskega razreza vezane plošče diplomsko delo - visokošolski strokovni študij Determination of optimal laser cutting parameters for cutting plywood graduation thesis - higher professional studies Pri obdelovanju lesa z laserjem je potrebno najti kompromis med kvaliteto obdelane površine, hitrostjo obdelovanja in ekonomskim vidikom proizvodnje. V diplomskem delu smo proučevali vpliv parametrov laserskega razreza topolove furnirne vezane plošče na kakovost reza. Topolovo vezano ploščo 3 različnih debelin (10 mm, 5 mm in 4 mm), smo rezali z različnimi hitrostmi rezanja in močmi laserja z namenom določitve optimalnih parametrov rezanja za kvaliteten rez. V izhodišču smo izbrali 3 jakostne stopnje laserskega žarka (20 W, 40 W, 60 W) ter različne hitrosti rezanja (od 6 mm/s do 56 mm/s). Na podlagi meritev globine in širine reza ter izračuna kota reza (koničnost robov) in ločilne energije, smo določili optimalno hitrost in moč laserskega razreza za izbrano debelino topolove furnirne vezane plošče. Za vezano ploščo nazivne debeline 10 mm so optimalni parametri rezanja 20 W in 6 mm/s, za vezano ploščo nazivne debeline 5 mm so optimalni parametri rezanja 20 W in 16 mm/s in za vezano ploščo nazivne debeline 4 mm so optimalni parametri rezanja 20 W in 20 mm/s. When using laser cutting in the processing of wood, it is necessary to find a compromise between the quality of the treated surface, the speed of processing, and the economic aspects of production. In this thesis, the influence of laser cutting parameters for cutting poplar veneer plywood was studied. Three different thicknesses (10 mm, 5 mm and 4 mm) of poplar plywood boards were cut at various speeds and cutting forces of the laser in order to determine optimal parameters for the quality of cutting. As a starting point, three intensity levels of the laser beam (20 W, 40 W, 60 W) and the different cutting speeds (from 6 mm/s to 56 mm/s) were chosen. Based on measurements of the depth and width of cut and of calculation of the cutting angle (tapered edges) and separation energy, we determined the optimum speed and power of laser cutting for the selected thickness of poplar veneer plywood. For 10 mm veneer plywood, they are 20 W and 6 mm/s. For 5 mm veneer plywood, the optimal parameters of laser cutting are 20 W and 16 mm/s. For 4 mm veneer plywood, the optimal parameters of laser cutting are 20 W and 20 mm/s. furnirna vezana plošča lasersko rezanje rezalna hitrost veneered plywood laser cutting cutting speed true false false A.
