微量润滑（MQL）是一种高效、绿色、环保的切削液应用方法。这项研究提出了不同的植物油基纳米流体MQL磨削各种工件材料的加工特性。三种润滑剂类型的性能（即，纯棕榈油、MoS2纳米流体和Al2O3纳米流体）和三种类型的材料（即，Inconel 718、球墨铸铁和AISI 1045钢）的力比、比磨削能和G比进行了评价。通过正交试验，得到了相同试验条件下润滑剂和工件材料的最佳工艺组合。通过对工件表面形貌和磨屑形貌的评价，验证了优化结果。实验结果表明，不同的加工特性的材料时，不同的工件加工使用不同的MQL润滑剂。MoS2纳米流体MQL适用于加工软质中碳钢，如45钢，而Al2O3纳米流体适用于加工高强度和硬度的材料，如镍基合金。
Minimum quantity lubrication (MQL) is an efficient, green, and eco-friendly method of applying cutting fluids in machining processes. This study presents the processing characteristics of different vegetable oil-based nanofluid MQL for grinding various workpiece materials. The performance of three lubricant types (i.e., pure palm oil, MoS2nanofluid, and Al2O3nanofluid) of good lubrication performance and three types of materials (i.e., Inconel 718, ductile cast iron, and AISI 1045 steel) was evaluated in terms of force ratio, specific grinding energy, and G ratio. The optimal processing combination of lubricants and workpiece materials under the same experimental conditions was obtained using orthogonal experiment. Optimization results were verified by evaluating the morphology of the workpiece surface and grinding debris. Experimental results show the different processing characteristics of materials when various workpieces are processed using dissimilar MQL lubricants. MoS2nanofluid MQL is suitable for machining soft medium carbon steels, such as 45 steel, while Al2O3nanofluid is suitable for machining materials of high strength and hardness, such as nickel-based alloys.
