Vrednotenje površin po graviranju z AVC : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoMiklavec, Žiga, 1993-Proces obdelave z abrazivnim vodnim curkom (AVC) spada med konturne postopke rezanja, pri katerem visokohitrostnemu vodnemu curku dodajamo abrazivna zrna. Voda skupaj z abrazivom udarja ob ... obdelovanec, pri čemer odnaša material. Rezalni postopek je primeren za obdelavo različnih materialov, med drugim kovin, kamna, stekla in organskih materialov, brez prisotnosti toplotno vplivanega območja. Kljub dobrim lastnostim postopka obdelave največjo slabost predstavlja manjša natančnost rezanja. Ena izmed tipičnih značilnosti obdelave pri rezanju z AVC je nastanek brazdavosti površine. V delu smo opravili pregled literature v povezavi z značilnimi pojavi na površini materiala po rezanju z AVC. V eksperimentalnem delu naloge smo na obdelovani stroj za rezanje z AVC namestili dozirni sistem z vrtečim se kolesom, ki dovaja abraziv v mešalno komoro rezalne glave ter z njim opravili graviranje materiala. Z namenom iskanja morebitnih povezav za nastanek brazdavosti na površini obdelovanca smo v aluminijevo zlitino in konstrukcijsko pločevino naredili gravure globin do nekaj milimetrov, pri čemer smo globino reza povečevali s spreminjanjem nastavitvenih parametrov obdelave. Z digitalnim mikroskopom smo analizirali topografijo površin gravur ter z obdelavo podatkov rezultate ovrednotili. Rezultate smo prikazali s pomočjo grafov moči spektralne gostote. Ugotovili smo, da moč spektralne gostote narašča pri določenih frekvencah, ki so posledica večanja globine reza.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
