    The purpose of this study is to evaluate the sustainability indicators of aluminium hybrid composite material (AA6082 + 3wt%SiC+1wt .%MoS2) under different eco-friendly cooling strategies such as dry, MQL, LCO2, MQL + LCO2. A variety of social, economic, and environmental aspects of sustainability indicators such as Total cycle time (TTCT), productivity, Total machining cost (CT) Energy consumption (Ec), Carbon emission analysis (Cee), Cutting force (CF) and Surface Roughness (Ra) are considered in this study. A novel sustainable approach of overall equipment effectiveness (OEE) is included to evaluate the true productivity under different cooling en-vironments. By comparing all the machining conditions, it was found that hybrid (CO2 + MQL) resulted the highest OEE as 95.63% and very low carbon emission of 0.6 kg-CO2 under higher cutting speed of 120 m/min and feed rate of 0.1 mm/rev at 1 mm depth of cut.

    Both the product and the manufacturing process must be sustainable in today's modern world. Traditional machining methods are undesirable when working with heat-resistant alloys. These methods could be more efficient and can be maintained over time. As the world progresses to sustainability, many people are working to integrate this concept into the industrial process. In the manufacturing industry, the evaluation of sustainability carries immense significance in ensuring product quality, promoting operators' safety and well-being, and preventing any form of environmental degradation or pollution. Concerning this regard, the main objective of the present study is to assess the sustainability parameters during the drilling of Alloy 20 material under different environmental conditions such as minimum quantity lubrication (MQL) and cryogenic and hybrid methods. The study is conducted in two stages, and in the first stage, the most impactful sustainable indicators, i.e., energy consumption, carbon emissions, total cycle time, and cost, have been evaluated. In the second phase of the investigation, the machining analysis of surface roughness, cutting forces, and circularity was determined under different conditions. The results showed that the hybrid cooling condition exhibited better technical, quality, and economic sustainability. Thus, it is important to note that selecting appropriate cooling conditions can contribute to achieving sustainability in manufacturing processes and that the hybrid cooling method aids industries in moving towards sustainable production systems that, in turn, contribute to a more environmentally conscious and efficient economy.
