Abstract Emulsion based cutting fluids are traditionally used to extract the heat in cutting zone but are found non-sustainable due to adverse impact on environment and worker's health. To provide a superior machining performance with lower consumption of cutting oil, indigenously developed electrostatic minimum quantity lubrication (EMQL), hybrid NPs immersed EMQL (HNEMQL) and electrostatic lubrication (EL) machining techniques are proposed for the practical range of cutting parameters. Overall, 10.75%, 4.88% and 2.25% lower values of power consumption are found in HNEMQL as compared to dry, EL and EMQL respectively for turning 15–5 precipitation-hardened stainless steel (PHSS). The better results of surface roughness and chip reduction coefficient are found for EL and HNEMQL techniques respectively as compared to other cutting fluid strategies.

内部开发环保润滑技术（EMQL、纳米粒子+EMQL 和 EL）以提高 15-5 PHSS 的加工性能

摘要 基于乳化液的切削液传统上用于提取切削区的热量，但由于对环境和工人健康产生不利影响，因此被发现是不可持续的。为了以更低的切削油消耗提供卓越的加工性能，针对切削参数的实际范围提出了自主开发的静电最小量润滑 (EMQL)、混合 NPs 浸入式 EMQL (HNEMQL) 和静电润滑 (EL) 加工技术。总体而言，在车削 15-5 沉淀硬化不锈钢 (PHSS) 时，HNEMQL 的功耗值分别比干法、EL 和 EMQL 低 10.75%、4.88% 和 2.25%。
