20.500.12556/RUL-136473 Analiza vpliva kriogenega frezanja na 99,5% čistem aluminiju Analysis of cryogenic machining influence on 99.5% Aluminum V tem delu je predstavljena primerjava hladilno-mazalnega učinka, pri obdelavi čistega aluminija na frezalnem stroju med klasičnim HMT (emulzijo) in kriogenim kapljevitim CO2 mešanim z razpršenim oljem (MQL). Primerjava je prikazana s pomočjo odrezovalnih sil med obdelavo, izmerjeno hrapavostjo površin in obrabo orodja. Raziskali in primerjali smo tudi vplive HMT pri različnih obdelovalnih hitrostih ter pokazala, da lahko s pomočjo kriogene obdelave desežemo višje odrezovalne histrosti z manjšo obrabo orodja. This work focuses on a comparison of the cooling and lubricating effect in the machining of pure aluminum on a milling machine between conventional CLF (emulsion) and cryogenic liquid CO2 mixed with dispersed oil (MQL). The comparison is shown with measured cutting forces during machining, measured surface roughness and tool wear. We also investigated and compared the effects of CLF, at different machining speeds and discovered, that with the help of cryogenic machining we can achive higher cutting speeds and feeds with smaller tool wear. aluminij hlajenje mazanje kapljeviti CO2 emulzija kriogeno obdelava frezanje aluminium lubrication cooling liqud CO2 emulsion criogenic milling true false false [Ž.
