Applications of vegetable oil-based cutting fluids are becoming increasingly popular in machining due to negative environmental and health effects caused by the conventional mineral oils. However, suitability of lesser-known vegetable oils as cutting fluids has been minimally reported. This study was designed to investigate the performance of a lesser-known vegetable oils as cutting fluids in machining. The jatropha oil was characterized to identify phytochemical, physiochemical and lubricity related properties. The effects of jatropha oil emulsion on surface roughness, cutting temperature and chip formation in turning AISI 1525 steel alloy with coated carbide tool were investigated and compared with mineral oil. Taguchi L₉ (3³) orthogonal array was used for the experimental plan. In addition, multi-response optimization was conducted using Grey relational analysis (GRA). Jatropha oil-based cutting fluid achieved better performance than mineral oil-based cutting fluid in most machining conditions. The GRA results revealed that optimal multi-response performance of the jatropha oil-based cutting fluid and commercial mineral oil-based cutting fluid can be achieved using the same cutting velocity (355 m/min) and feed rate (0.10 mm/rev) but with varying depth of cut of 1.00 and 1.25 mm, respectively.

由于常规矿物油对环境和健康的负面影响，植物油基切削液的应用在机加工中变得越来越普遍。然而，鲜为人知的是鲜为人知的植物油作为切削液的适用性。这项研究旨在研究鲜为人知的植物油在加工中作为切削液的性能。麻疯树油的特征在于鉴定与植物化学，物理化学和润滑性相关的特性。研究了麻风树油乳液对涂层硬质合金车削AISI 1525合金表面粗糙度，切削温度和切屑形成的影响，并与矿物油进行了比较。田口L ₉（3 ³）正交阵列用于实验计划。此外，使用灰色关联分析（GRA）进行了多响应优化。在大多数加工条件下，麻风树油基切削液的性能要优于矿物油基切削液。GRA结果显示，在相同的切削速度（355 m / min）和进给速度（0.10 mm / rev）相同的情况下，麻疯树油基切削液和市售矿物油基切削液可以实现最佳的多响应性能，但是切削深度分别为1.00和1.25毫米。
