20.500.12556/RUL-156434 Analiza rezalnih sil in obrabe orodja pri obdelavi nerjavečega jekla Analysis of cutting forces and tool wear in milling of stainless steel V magistrskem delu je predstavljena primerjava mehanske obdelave nerjavečega jekla s tremi različnimi načini hlajenja: emulzija, zrak in ogljikov dioksid ▫$(CO_2)$▫, mešan z minimalno količino oljne megle (MQL). Glavna elementa raziskave sta rezalne sile in obraba orodja po dveh urah CNC obdelave s povečanimi parametri od priporočenih vrednosti. Pokazali smo, da sta za obdelavo nerjavečega jekla primerna emulzija in ▫$CO_2+MQL$▫, obdelava z zrakom pa se je izkazala za neprimerno metodo hlajenja orodja. The master's thesis presents a comparison of mechanical processing of stainless steel using three different cooling methods: emulsion, air, and carbon dioxide ▫$(CO_2)$▫ mixed with a minimal quantity lubrication oil mist (MQL). The main elements of the research were cutting forces and tool wear after 2 hours of CNC machining with increased parameters beyond the recommended values. We demonstrated that emulsion and ▫$CO_2+MQL$▫ are suitable for processing stainless steel, while air cooling proved to be an unsuitable method for tool cooling. nerjaveče jeklo CNC obdelava rezalne sile obraba orodja emulzija zrak kapljeviti ogljikov dioksid minimalna količina oljne megle stainless steel CNC machining cutting forces tool wear emulsion air leaking carbon dioxide minimum quantity lubrication true false false [G.
