Sustainability Enhancement in Machining of DTC Titanium Alloy through Integrated Impact Assessment of Various Lubrication Strategies

Abstract

Machining difficult-to-cut materials like Ti-6AL-4V is characterized by various negative environmental and social impacts, leaving a burden on the environment. Stringent ecological conditions imposed by the government made it necessary to develop a sustainable machining solution. The word "sustainability" refers to the unit process, which is long-term viable from an economic, environmental, social, and quality point of view. Furthermore, because production and operations managers need to know how the machining process contributes to Sustainability, the necessity to measure the Sustainability of machining activities has been recognized. As a result, this study presents a novel paradigm for evaluating the impact of various lubrication strategies on machining operations from an economic, environmental, and product perspective, which measures the Machining operation's Sustainability. The milling process is the focus of this study due to its frequent application in complex industrial jobs. The MQL milling with the lowest impact score of 27.6 is found sustainable.
