Cutting fluids play a crucial role in machining processes by providing cooling to the cutting tool and workpiece surface, lubricating the tool-workpiece interface, and removing chips from the cutting zone. The main objective of using cutting fluids is to reduce temperature and minimize frictional wear through effective cooling and lubrication. As a result, mineral, vegetable, and animal oils have emerged for cutting fluid. Though, mineral oil-based cutting fluid also presents significant concerns regarding environmental impact, health hazards, and the challenges of recycling and disposal. Compared to mineral oils, vegetable oils exhibit favourable characteristics such as a higher viscosity index, flash point, lubricity, and lower evaporative losses. Vegetable oils can be classified as edible or non-edible, and several studies have demonstrated the effective utilization of edible vegetable oils as environmentally friendly cutting fluids in machining operations. However, the current scenario poses limitations on harnessing edible oils for lubricant production due to the increasing global demand and limited availability. In this study, the focus was on using non-edible vegetable oils, specifically Neem and Karanja oils, as cutting fluids in different ratio blends for turning mild steel. The objective was to assess the effect of these blends on surface roughness. To conduct the experiments, employed the Taguchi L9 orthogonal array experimental design plan.
