20.500.12556/RUL-102 Lasersko rezanje vlaknene plošče diplomsko delo (visokošolski strokovni študij) Fiber board cutting using laser graduation thesis (higher professional studies) V industriji se pogosto pojavlja vprašanje, kako bi lahko proizvedli več, v krajšem času, z boljšim izkoristkom časa in materiala, bolj kvalitetno, in če bi lahko to dosegli že z zamenjavo tehnološke opreme. Skušali smo ugotoviti, če je laserska tehnika, že uporabljana na mnogih zelo različnih področjih, primerna tudi za rezanje vlaknenih plošč. S CO2 laserskim sistemom smo razrezali 9 preskušancev 3 debelin, po metodi lameliranja z različnimi laserskimi parametri. Analizo širine in površine laserskih rezov smo opravili po metodi laserske triangulacije. Opazovali smo vpliv rezalne hitrosti, debeline plošč, pomožnega laserskega plina in položaja fokusne razdalje na širino reza, na katerega sta najbolj vplivali rezalna hitrost in položaj fokusne razdalje. Z naraščajočo rezalno hitrostjo in s pomikom fokusne razdalje bolj proti sredici plošče se je širina reza manjšala. Z analizo površin laserskih rezov smo ugotovili hrapavost, ukrivljenost in poševnost rezanih površin. Največji vpliv na te parametre sta imeli rezalna hitrost in debelina materiala, z njunim naraščanjem se je povečevala hrapavost in poševnost površin, radij ukrivljenosti pa zmanjševal. The never ending question asked in our industry is how to produce more, better, using less time and material, and if all these can be done by changing the technological equipment. Therefore, we tried to find out if the laser technology used in many different areas, could also serve for cutting of fiber boards. To do it the CO2 laser system was used. Using a method of lameling with various laser parameters, 9 testers of different thickness were cut. The analysis of width and surface of laser cuts was performed by a laser triangulation method. The influence of cutting speed, board thickness, additional laser gas, and position of focus distance on width of the cut were observed. The main factors influencing the width of cut were cutting speed and the position of focus distance. Rising the cutting speed and moving the focus distance towards the middle of board thickness, the cutting width diminishes. The roughness, curvature and obliquity of cut surfaces were assessed by an analysis of laser cut surfaces. The cutting speed and thickness of material have the main influence on these parameters. Increasing the cutting speeds and material thickness the roughness and obliqueness of surfaces rise, but the curving radius reduces. vlaknena plošča lasersko rezanje širina reza ukrivljenost hrapavost fiber board laser cutting cut width obliqueness curvature roughness true false false [P.
