Abstract
The main purpose of using cutting fluid during machining processes is to reduce the cutting temperature and friction, and to wash away chips from the cutting zone. However, excessive use of conventional cutting fluid negatively influences human health and environment. Therefore, much research has attempted to improve cutting fluid performance with superior tribological and thermal properties, and to reduce the amount of cutting fluid to minimize machining cost and impact on environment. Recently, Minimum Quantity Lubrication (MQL) technique has been widely investigated as a good alternative to flood coolant. Although MQL improves machining results, its removal heat capability still needs to improve. In this paper, in order to enhance the thermal conductive and viscosity of MQL, nanoparticles were dispersed to make nanofluid coolant. Nanofluids have attracted the attention of investigators due to their good high thermal conductivity and ability to remove heat. In this study, the effect of the cutting speed, feed rate, and nanoparticle concentrations on machining titanium Ti-Al6-V4 alloy were investigated by performing ANOVA analysis. The nanofluid coolant was prepared by adding Aluminum Oxide (Al 2 O 3 ) nanoparticles to base fluid (vegetable oil) at different weight concentrations (0, 2, and 4%wt).

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
