Uvedba računalniške tomografije kot metrološke metode v livarski proces : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoHafnar, Ana, strojnicaPoroznost kot zračni mehurčki v procesu litja predstavlja največji izziv, saj prisotnost le-teh vpliva na mehanske lastnosti ulitka. Za odkrivanje poroznosti se uporabljajo različne metode, med ... katerimi nekatere pri odločitvah vključujejo človeški faktor. Zadnja in najmodernejša metoda je uporaba računalniške tomografije, ki nam prostorsko, vrednostno in celovito prikaže nepravilnosti v materialu, kar je bilo v večini primerov v preteklosti nemogoče oziroma ne dovolj definirano ali dosegljivo za neko uporabno vrednost. V magistrskem delu so v teoretičnem delu najprej predstavljene generacijsko in kvalitativno različne metode zaznavanja poroznosti. Predstavljene so teoretične osnove statističnega nadzora procesa in metode stroškov kakovosti. V nadaljevanju je v eksperimentalnem delu na reprezentativnem ulitku predstavljeno merilno okolje in načini merjenja poroznosti. Izvedene so meritve poroznosti z rentgenom, ki vključuje človeški faktor, in CT merilnim strojem. V rezultatih je nato predstavljena analiza meritev in vpliv načina merjenja na kakovost merilnih podatkov. V zaključku naloge je predstavljena tudi primerjava analize stroškov kakovosti za posamezen način merjenja poroznosti.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
