Evaluation of the Role of Dry and MQL Regimes on Machining and Sustainability Index of Strenx 900 Steel

Sustainable technologies draw attention in the machining industry thanks to their contributions many aspects such as ecological, economic, and technological. Minimum quantity lubrication (MQL) is one of these techniques that enable convey high pressurized cutting fluid toward zone small oil particulates. This study examines potency MQL technology versus dry conditions on quality during milling structural Strenx 900 steel within sustainability index. High strength toughness properties make this a hard-to-cut material providing an important opportunity test performances environments. The outcomes experimental data demonstrated superior enhancing significant characteristics namely surface roughness (up 35%), flank wear 94%), mechanisms, energy 28%), temperatures 14%). Furthermore, after analyzing main headings sustainable indicators, provided same (+5) desirability value with medium. work presents comparative approach for improved machinability industrially materials by questioning impact methods.
