Abstract: The study assessed the efficacy of cutting fluids derived from non-edible vegetable oils, focusing on flood cooling during mild steel turning. Karanja and neem oils were blended in varying ratios, and MIRANDA S-400 high-speed steel tools measured flank wear during machining. The Taguchi method, employing an L9 orthogonal array, analysed the impact of cutting fluid on tool flank wear, correlating variables like cutting speed, cutting feed and depth of cut. Statistical techniques including S/N ratio and analysis of variance were utilised, with Minitab 18 software for analysis. Optimal machining parameters (v₁-f₂-d₁-CF₁) were identified, resulting in a 48.30% reduction in tool flank wear. This research provides valuable insights into minimising wear on tool flanks during machining processes.
