A critical assessment of lubrication techniques in machining processes: a case for minimum quantity lubrication using vegetable oil-based lubricant (2013, methodology): “…the technique, if properly employed can provide significant improvement in both productivity and product quality and hence, overall machining economy even after covering the additional cost of cryogenic cooling system and cryogenic fluid ( Mirghani et al., 2007; Dhar & Kamruzzaman, 2007).”
Cryogenic Machining-Induced Surface Integrity: A Review and Comparison with Dry, MQL, and Flood-Cooled Machining (2014, background): “Cryogenic machining of conventional steels also has been shown to produce better surface quality (Dhar et al., 2001; Dhar et al., 2002; Dhar and Kamruzzaman, 2007; Paul et al., 2001) due to its positive effect on reducing tool-wear and built-up-edge at various feed rates and cutting speeds which is ”
