Abstract

This study examines the influence of rice straw-derived cellulose fiber inclusion in coconut oil-based cutting fluid on the flank wear of High-Speed Steel (HSS) tools during the turning of ST 37 steel. The objective is to provide an alternative cutting fluid that is environmentally friendly, sustainable, and cost-effective, as traditional petroleum-based fluids pose ecological and health concerns and contribute significantly to production costs. Cellulose extracted from rice straw was mixed into coconut oil at concentrations of 0%, 2%, 4%, and 6%. Turning operations were conducted using consistent cutting parameters, and the flank wear of the HSS cutting tool was measured using a digital stereo microscope. The resulting data were analyzed using ANOVA and the Tukey HSD test to determine the statistical significance of observed differences. The results showed that increasing the concentration of cellulose in the cutting fluid generally reduced tool wear. The highest average flank wear was observed in the control group (0% cellulose) at 204.801 µm, while the lowest was recorded at 6% cellulose at 144.567 µm. Only the difference between the 0% and 6% concentrations was statistically significant (p-value < 0.05), indicating that a higher cellulose concentration has a beneficial effect on tool life. The findings suggest that rice straw cellulose is an effective solid additive in coconut oil, enhancing its lubricating and cooling capabilities. This study supports the utilization of agricultural waste as a sustainable additive in cutting fluids, contributing to green tribology and more eco-friendly machining practices.
