The influence of the Ultra Fine Bubble (UFB) inserted Coconut oilbased metalworking fluid (MWF) on tool wear modes and mechanisms in turning of Inconel 718

Abstract

A comprehensive analysis of the tool wear modes and mechanisms was performed to clarify the influence of the ultra-fine bubble (UFB) inserted coconut oil-based metalworking fluid (COCO) for extended tool life for machining Inconel 718. The wear progression was examined for the interrupted cutting intervals while using UFB inserted COCO and the tool performance was evaluated according to the ISO 3685;1993 standard. Usage of the UFB inserted COCO has demonstrated 30% extended tool life and lower adhesion compared to the commercially available synthetic oil-based metalworking fluid (MWF (SynO)). The clarifications relevant to the performance and the increment of the tool life on machining of Inconel 718 while using the UFB assorted green MWF added significant industrial value to the sustainable machining context of difficult-to-cut materials.
