        abstract = {The escalating global demand for sustainable and environmentally responsible manufacturing has intensified research into biodegradable lubricants and nano-enhanced cooling technologies for industrial machining operations. Conventional mineral-oil-based cutting fluids pose serious environmental, health, and waste-disposal challenges incompatible with green manufacturing philosophies. To address these shortcomings, biodegradable vegetable oils reinforced with engineered nanoparticles have emerged as a highly promising alternative. In the present investigation, Silicon Carbide (SiC) nanoparticles dispersed in refined palm oil are deployed under Minimum Quantity Lubrication (MQL) conditions for the sustainable turning of AISI 1040 medium-carbon steel. SiC–Palm Oil nanofluids are prepared by a two-step synthesis route at volume concentrations of 0.1%, 0.2%, and 0.3%, and comprehensively characterised for thermal conductivity, density, dynamic viscosity, flash point, and colloidal stability. Fourier Transform Infrared Spectroscopy (FTIR) and Zeta-Potential analysis are employed to verify chemical integrity and dispersion stability. Turning experiments are conducted on AISI 1040 steel under MQL delivery using a Taguchi L9 Design of Experiments (DOE) framework. Performance metrics — surface roughness, cutting temperature, cutting force, and flank tool wear — are simultaneously optimised using Principal Component Analysis (PCA). The study demonstrates that biodegradable SiC–Palm Oil nanofluids constitute a technically superior and environmentally benign substitute for conventional cutting fluids.},
