An investigation is made into the lubrication capabilities of solid-lubricated liquid carbon dioxide (LCO2)incomparison toflood lubrication, straight LCO2and oil-lubricated LCO2(MQL). The coefficient of friction isdetermined via tribological experiments, similar to machining, using an open tribometer which features anuncoated carbide insert sliding against a workpiece. Tribological experiments reveal superior performance ofsolid-lubricated LCO2. The milling experiments as well indicate that solid-lubricated LCO2significantlyreduces wear. The machined-surface topography is examined using high-magnification SEM, which showsno presence of adhered solid particles on the workpiece surface, providing a completely dry machining pro-cess.
