Recent Advancements in Machining Processes Using Minimum Quantity Lubrication and Nanofluids

Abstract Modern manufacturing relies heavily on machining operations like turning, drilling, milling, and grinding; thus, it is critical to optimize these operations for efficiency and sustainability. Nanofluids and minimum quantity lubrication (MQL) have come to light as a potentially effective way to lessen environmental effects while increasing machining efficiency. The use of nanofluid-based MQL in these important machining processes is thoroughly examined in this article. The usage of nanofluids including nanoparticles like Al2O3, CuO, and TiO2 has been shown to significantly increase cooling and lubrication, reduce tool wear, and improve surface smoothness. Cutting forces, heat dissipation, and material removal rates are among the key performance parameters that are carefully assessed in various machining processes. The article also discusses the benefits of using nanofluid-assisted MQL in terms of the economy and environment, such as decreased waste production and lubricant use. Other issues covered include the necessity for additional experimental validation, system integration, and the stability of nanoparticle dispersion. In summary, the purpose of this review is to shed light on the potential of nanofluid-based MQL as an economical and environmentally responsible substitute for traditional machining techniques.
