Damir Grguraš, Franci Pušavec
Doktorska disertacija
Oznake: kriogeno frezanje;kriogeno odrezavanje;odrezovalne razmere;tekoči ogljikov dioksid;enokanalni dovod;hladilna sposobnost;temperatura odrezavanja;mazalna sposobnost;analiza toka;
V doktorskem delu je predstavljeno kriogeno frezanje (ang. cryogenic milling) z uporabo tekočega ogljikovega dioksida (ang. Liquid Carbon Dioxide - LCO2). Način enokanalnega dovoda (ang. single-channel supply) kriogenega medija, t.j. mešanice (a) LCO2 in (b) olja v obliki oljne megle - MQL (ang. Min ...

Oznake: flow analysis;flow velocity;droplet size;single-channel supply;liquid carbon dioxide - LCO2;minimum quantity lubrication - MQL;LCO2 assisted machining;
Single-channel supply of pre-mixed liquid carbon dioxide (LCO2) and minimum quantity lubrication (MQL) represents a state-of-the-art LCO2 assisted machining. However, to fully understand and optimize cooling and lubrication provided by the LCO2 + MQL, a fundamental media flow analysis is essential, ...
