Abstract:
The computerized numerical control (CNC) machining industry is facing challenging situations as it moves forward from using traditional cutting fluid management practices to green counterparts. This thesis aims to scrutinize associated factors of cutting fluid management (CFM) through an overview of cutting fluid usage scenarios and building causal relationships among the CFM factors to ensure green manufacturing practices in CNC machining industries in the Bangladesh. In this study, a field survey using a questionnaire was done to find out how cutting fluid is used and disposed of. A fuzzy Delphi technique was utilized to evaluate CFM factors identified from literature and expert opinions on physical, technical, economical, ecological, social, and legal aspects. Out of the 26 factors, 13 were found to be the most significant, with reuse and recycling facilities ranked number one. Using the grey-DEMATEL method, interdependence between the elements was assessed, and it was discovered that seven factors have an impact on the others. The study implies that priority-based consideration of cutting fluid management factors can be worth it to assure green manufacturing practices in CNC machining businesses.
