Enhancing Sustainability in Machining: Performance Evaluation of Graphene-Based Green Cutting Fluids in Minimum Quantity Lubrication (MQL) Turning

Abstract

This study explored the performance of a new type of graphene based green cutting fluids in minimum quantity lubricationmachiningprocess helps in sustainability through ecofriendly machining processes. The effectiveness of green cutting fluids nano-graphene with varying concentrations 0.4%, 0.8%, 1.2%, 1.6% and 2% isevaluated in turning process with minimum quantity lubrication. The machining carried out within the context of dry, wet, minimum quantity lubrication, and nano minimum quantity lubrication environments. Comparative study was carried out to analyse cuttingforce, temperatureand surface roughness inmachiningoperation with graphene nanofluids. The findings reveal a momentousdecrease in cutting force, cutting temperature, and surface roughness about 18.98%, 31.74%, and 24.23%, respectivelywhen utilizing 1.6% graphenenanofluids as compared to conventional coolants during wet machining. These results emphasize the promising potential of graphene-based green cutting fluids in enhancing the sustainability of machining processes, contributing to eco-friendly manufacturing practices.
