Banque- Hilsch Vortex tube plus MQL (RHVT + MQL), liquid nitrogen plus minimum quantity lubrication (N2+MQL), and liquid nitrogen (N2) are presented for turning Ti-6Al-4V utilizing CVD coated carbide insert. The tool wear, surface roughness, micro-hardness, specific cutting energy, and chip morphology are considered under sustainable cooling conditions and compared with the dry condition. The outcome revealed that the N2+MQL reduced the tons of annual coolant consumption attaining smooth surface quality, minimum built-up-edges of chips, and tool wear. Besides, minimum specific cutting energy and surface hardness achieved under N2+MQL among all cooling conditions. This endeavor is peculiar integrating sustainability and machining perspective under advanced cooling techniques for industrial application of Ti-6Al-4V.eninfo:eu-repo/semantics/closedAccessSurface integrityTitaniumTool wearTribological aspectsTurningArticle15310.1016/j.triboint.2020.1065822-s2.0-85089349520Q1WOS:000582755900021Q1
