摘要

X22CrMoV12-1 refractory heat-resistant high-strength stainless steel is primarily used in the machining and manufacturing of heavy-duty gas turbine compressor blades. To address the demand for green finishing of blades, this paper conducted cutting experiments on X22CrMoV12-1 steel under dry cutting, minimum quantity lubrication (MQL), cryogenic CO₂, and the Supercritical CO2 based minimum quantity lubrication (CMQL) process. Compared to dry cutting, CMQL demonstrated 52.2% reduction in cutting force at vs =80 m/min, 40.9% decrease in cutting temperature at vs =140 m/min, and only 15% increase in surface roughness Ra when ap was increased from 1.5 mm to 2 mm. Ultimately, tool wear decreased by 62.79%. Under the optimal CMQL process parameters obtained through grey relational analysis, specific energy consumption (SEC) and Ra values decreased by 31.27% and 40.54%, respectively, compared to dry cutting. Additionally, the CMQL process demonstrated a distinct advantage over MQL in reducing surface roughness, while exhibiting significant energy savings compared to cryogenic CO₂. CMQL employs lubrication-cooling synergy to reduce friction and intensive cooling, providing a reliable paradigm for sustainable compressor blade manufacturing that balances high precision with low energy consumption across a wide parameter window.
