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.
