This study evaluates the effects of new bio-based nanolubricants blend formulation on the machinability improvement during the turning Inconel 718 alloys. Different proportion of coconut oil (CO), sodium dodecylbenzenesulphonate (SDBS), cocoamidopropyl betaine (CAPB) with 0.5% of aluminium oxide (Al₂O₃) nanoparticles were blended according to the mixture-design methodology to form the nanolubricants emulsion. Machining responses of tool wear, surface roughness, cutting power and spindle power were comprehensively assessed. The analyses revealed that a combination of 107.14 g of CO, 22.5 g of SDBS, and 15.36 g of CAPB was an ideal formulation for attaining excellent tribological and machining efficiency in the turning of the aforementioned alloy. Suitability of the formulated bio-based nanolubricants was also confirmed in terms of toxicity, corrosion resistance, and biodegradability.

本研究评估了新型生物基纳米润滑剂混合配方对 Inconel 718 合金车削过程中可加工性改进的影响。不同比例的椰子油 (CO)、十二烷基苯磺酸钠 (SDBS)、椰油酰胺丙基甜菜碱 (CAPB) 与 0.5% 的氧化铝 (Al ₂ O ₃) 根据混合物设计方法混合纳米颗粒以形成纳米润滑剂乳液。综合评估刀具磨损、表面粗糙度、切削功率和主轴功率的加工响应。分析表明，107.14 克 CO、22.5 克 SDBS 和 15.36 克 CAPB 的组合是在上述合金车削中获得优异摩擦学和加工效率的理想配方。在毒性、耐腐蚀性和生物降解性方面也证实了配制的生物基纳米润滑剂的适用性。
