Abstract
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 environments. 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.
