摘要

Sustainability evaluation involves a structured procedure to appraise the impacts of an undertaking on the environment, society, and economy. It aims to determine whether the actions or decisions are in line with sustainable development goals and can provide long-term benefits while minimizing negative consequences on the planet and society. In the current competitive market, the idea of sustainability is progressively gaining significance in modern manufacturing practices. This research employs a multi-criteria decision-making framework to assess sustainability, specifically focusing on enhancing the machining performance of Inconel 690 superalloy through the utilization of eco-friendly lubricating/cooling agents. The results demonstrated significant improvements, including an 80.64% reduction in Flank wear, a 43.08% reduction in Surface roughness, a 15.58% reduction in Machining cost, an 11.57% reduction in Carbon emissions, and a 25.91% reduction in Noise generation under the Cryo-MQL medium compared to dry machining conditions. The sustainability index (SI) for Taguchi-designed sixteen experimental runs is determined by the Analytic Hierarchy Process (AHP) coupled with the Complex Proportional Assessment (COPRAS) approach. The AHP-COPRAS approach was chosen due to its ability to systematically integrate conflicting criteria while minimizing subjective biases, offering a more robust and comprehensive sustainability evaluation framework compared to other MCDM methods. This claims that a cutting speed of 80 m/min, feed of 0.1 mm/tooth, depth of cut of 1 mm, and Cryo-MQL medium are the best parametric settings for improving the sustainability of Inconel 690 machining. Furthermore, a sensitivity analysis of the criteria weights for ranking the machining experiments demonstrates the robustness of the proposed sustainability evaluation method.
