Metodologija vrednotenja površin po graviranju z AVC : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoHmeljak, ArjanRezanje z abrazivnim vodnim curkom (AVC) je vsestransko uporabljen postopek konturnega rezanja. Visok tlak pospeši vodni curek skozi ozko šobo, kjer mu primešamo abrazivna zrna. Zaradi visoke ... hitrosti in masnega doprinosa abrazivnih delcev dobimo curek z visoko kinetično energijo, kar odnaša material obdelovanca. Pri rezanju smo omejeni z debelino obdelovanca, ki je odvisna od moči samega curka. Za ta postopek je značilen pojav valovitosti, zlasti v spodnjem delu reza, ki je nezaželen, saj nam kvari geometrijo obdelovanca. V delu smo pregledali literaturo, povezano z značilnimi pojavi na površini obdelovancev po rezanju z AVC. V eksperimentalnem delu smo preučili vpliv masnega pretoka abraziva in podajalne hitrosti na značilnosti dobljene površine po graviranju z AVC ter iskali povezavo z nastajanjem valovitosti reza. Poskuse smo opravili na aluminijevi zlitini 5083. Globine gravur smo omejili na maksimalno 3 mm, kjer smo si pomagali z Zengovo enačbo za izračun teoretičnih globin reza. Eksponente te enačbe smo uspešno prilagodili in dosegli natančnejše napovedovanje globine graviranja. Rezultate smo vrednotili s pomočjo grafov močnostnega spektra, ter ugotovili, da se za izbrane parametre v razponu podajanja od 500 do 900 mm/min ter masnega pretoka od 12 do 48 g/min, nastanek valovitosti še ne pokaže.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
