Cutting fluids (CF) act as lubricating and cooling agents on the cutting zone during machining. Mostly, the oils derived from minerals act as CF, which adversely affect the environment and humans. Hence, replacing mineral oil with bio-oil derived from synthetic and vegetable oils is necessary. Bio-oil extracted from raw nonedible sources has become a reliable source for green cutting fluids in recent years. Bio-oil usage in machining eliminates numerous health issues such as ingestion, hazardous aerosols, and skin irritations produced by conventional cutting fluids. This study examines attaining renewable manufacturing by employing eco-friendly bio-oil cutting fluid. This study’s objective is to examine the performance of transesterified mesquite (Prosopis juliflora) oil (MO) as bio-oil-based CF. Post conversion of mesquite oil to methyl ester (MME), MME was inspected for, density, and viscosity as per the ASTM conditions. MME was compared with MO and synthetic ester (SE) on the orthogonal cutting condition to examine the suitability. Results revealed that the bio-oil provided better and natural lubrication than a synthetic ester. Further, it also improved the lubrication which improved the surface finish than a synthetic ester. Higher-lubricating property forms a strong film layer on the workpiece surface and lowered the working temperature than a synthetic ester. Hence, it is concluded that MME acts as an improved lubricant and shall be a potential candidate to replace synthetic ester as a cutting fluid.

切削液 (CF) 在加工过程中充当切削区的润滑剂和冷却剂。大多数情况下，从矿物中提取的油充当 CF，对环境和人类产生不利影响。因此，有必要用从合成油和植物油中提取的生物油代替矿物油。近年来，从非食用原料中提取的生物油已成为绿色切削液的可靠来源。加工中使用生物油可消除许多健康问题，例如传统切削液产生的摄入、有害气溶胶和皮肤刺激。本研究探讨了通过使用环保生物油切削液实现可再生制造。本研究的目的是检查酯交换牧豆树 ( Prosopis juliflora) 油 (MO) 作为生物油基 CF。在将豆科植物油转化为甲酯 (MME) 后，根据 ASTM 条件检查 MME 的密度和粘度。在正交切削条件下，将 MME 与 MO 和合成酯 (SE) 进行比较，以检验其适用性。结果表明，与合成酯相比，生物油提供了更好的天然润滑作用。此外，与合成酯相比，还提高了表面光洁度的润滑性。较高的润滑性能在工件表面形成坚固的膜层，并比合成酯降低工作温度。因此，得出的结论是，MME 作为一种改进的润滑剂，应该是替代合成酯作为切削液的潜在候选者。
