Popis: The excessive use of the conventional lubricants has resulted in environmental pollution. Therefore, there are various attempts that have been made to achieve sustainable machining through the development of new cutting fluid and coolant. This study investigated the influence of various nanoparticle-based vegetable oils on the turning of Inconel 718 using ceramic cutting insert. The vegetable oils used in this study were palm oil, coconut oil and olive oil. The nanoparticle was Al2O3 nanoparticles. These oils were mixed with the Al2O3 nanoparticles respectively using magnetic stirrer. The machining was carried out in OPTIturn D 360 × 1000 Conventional Turning Lathe. Minimum quantity lubrication (MQL) method was employed in the experiment to minimize wastage of oils. 9 experiments were performed based on the Taguchi’s L9 orthogonal array to obtain the optimum results of the process at the same time reduce the process variation. Signal to noise (S/N) ratio was used to determine the most effective cutting parameter on machining characteristics during turning operation. Various machining parameters were applied such as cutting speed and feed rate while output response were cutting temperature, tool wear and chip morphology. Results indicated that effect of cutting temperature and tool wear was better under palm oil mixed with Al2O3 nanoparticle. Meanwhile, feed rate was the most contributive factor affecting chip morphology under palm oil mixed with Al2O3 nanoparticle. Based on the result in this study, palm oil mixed with the Al2O3 nanoparticle was found to outperform coconut oil and olive oil as cutting fluid.
