Kompenzacija dimenzijskih odstopanj pri laserskem rezanju : diplomska naloga visokošolskega strokovnega študijaPeternel, Jernej, 1982-Lasersko rezanje je najbolj razširjen postopek za razrez pločevine. Pri tem zaradi vnosa toplote v material nastanejo zaostale napetosti, ki so vzrok nezaželenih dimenzijskih odstopanj. Iskali smo ... način, s katerim bi lahko zmanjšali dimenzijska odstopanja in se izognili potrebi po testnem izdelku. Laserske razreze iz konstrukcijskega in nerjavnega jekla različnih debelin smo opravili na stroju Trumpf 600. Za vsako dimenzijo, debelino in vrsto materiala smo izrezali vzorčne kose in predstavili meritve v preglednicah in grafično. Dodatno smo za vzorce uporabili različne hitrosti reza in ugotavljali vpliv dolžine vzorca na velikost skrčkov. S pridobljenimi podatki smo nastavili empirične modele. S programom Matlab smo izpeljali polinomsko enačbo. Za merjenje izdelkov smo uporabljali digitalna in ročna kljunasta merila. Ugotovili smo, da so dimenzijska odstopanja večja pri večjih debelinah vzorca, manjših širinah vzorca, pri nerjavni pločevini in pri manjših hitrostih reza. Velikost skrčkov se je spreminjala linearno s hitrostjo reza in z dolţino vzorca. Bistvenih razlik med rezultati, dobljenimi z merjenjem, in rezultati, dobljenimi s polinomsko enačbo, ni bilo. Uspeli smo narediti preglednico za ocenjevanje skrčkov pred samim merjenjem. Na podlagi rezultatov bo moč v prihodnje velikost skrčkov določiti že pred prvim laserskim rezom.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
