This study presents an innovative and sustainable approach for improving the performance of minimum quantity lubrication (MQL) machining by addressing the limited cooling and lubrication capacity of vegetable-based cutting fluids. A novel nanocutting fluid was developed using corn oil as a biodegradable base and calcium carbonate (CaCO3) nanoparticles synthesized from scallop shell waste as ecofriendly additives. The innovation lies in converting marine waste into high-performance nanomaterials and establishing the optimal nanoparticle loading threshold for enhanced machining performance. CaCO3 nanoparticles (0–0.20 wt%) were characterized by a spherical morphology, a calcite crystal phase, and an average crystallite size of 52.18 nm. Incorporating nanoparticles improved the thermophysical (density, viscosity, thermal conductivity, and stability), rheological (Newtonian flow behavior), and tribological (tool wear, surface roughness, and cutting temperature) of the base fluid. The optimal concentration of 0.15 wt% resulted in notable reductions in tool wear (by 36 %), surface roughness (by 28 %), and cutting temperature (by 22 %) compared with pure corn oil under identical MQL conditions. The excessive concentration (0.20 wt%) caused agglomeration and degraded the system performance. This work demonstrates the feasibility of using shell waste–derived CaCO3 nanoparticles to develop a cost-effective, biodegradable, and high-performance nanocutting fluid, thereby offering practical insights for optimizing green machining operations in sustainable manufacturing. © 2025 The Society of Manufacturing Engineers
