Vegetable oil is a liquid that has great potential and many advantages as the base material for cutting fluids used in machining processes. Mineral oil reserves will run out and are not environmentally friendly, so it is necessary to look for alternatives. Nanotechnology is currently widely applied to lubricants as additives. This study aims to determine analysis the volume fraction variation of calcium carbonate (CaCO3) nanoparticles as a bio-based lubricant additive as cutting fluid for sustainable machining. Calcium carbonate can be a protective layer from direct contact friction between materials that have anti-wear properties. Calcium carbonate from scallops shell as an additive was synthesized and then characterized using Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), and Fourier Transform Infra-Red (FTIR). Calcium carbonate from scallops shell used as an additive has a crystal size of 35.484 nm and including an irregular round agglomeration morphology structure. The results of density and viscosity are directly proportional to the magnitude of the variation of the volume fraction of nanoparticles, the higher the volume fraction, the value of density and viscosity will also increase, besides that the viscosity value is observed to decrease with increasing temperature. The highest density value was 804.7458 kg/m3 at 0.2% volume fraction variation, while the lowest density value was 765.1670 kg/m3 at 0% volume fraction variation. While the highest viscosity value was obtained at 0.2% volume variation in all variations of temperature and rotor rotational speed. © 2024 American Institute of Physics Inc.. All rights reserved.
