Conventional Milling Machine into CNC Machine Tool Remanufacturing, Eco-comparison Ratio Based Analysis

Abstract

Aims: Machine tool remanufacturing input material, energy and Co2 emissions are assessed to help conclude feedbacks about environmental benefits and burdens, what is necessary to enable educational institutions to conduct remanufacturing of machine tools as a business to deliver closing the loop supply chain for sustainable manufacturing. Study Design: Bridgeport manual milling machine is remanufactured within insights of new eco-design ideas to change it into CNC vertical milling machine where machine enabled to be flexible to embed cheap emerged CNC technology. Thus enough data can be acquired to be analyzed for feasibility study.  Methodology: A step by step case study of CNC machines technology introduction into conventional machine architecture is illustrated. Modules of ball screws and ball linear guide ways are embedded by means of magnetic mechanical flexible interfaces. Servo motors and CNC controller are used to deliver computer numerical control. Literature comparison and calculation are made to find eco-audit of the remanufacturing process. Results: Melting point of N35 Neodymium is compared with mean melting point of Cast Iron to exploit well-defined eco-audit of Cast Iron literature through defining ECR (eco-comparison ratio). Conclusion: To fulfill remanufacturing, eco-design enables modules of linear slides rails-carriages and ball lead screws to be assembled to conventional milling machine, which can be certain through magnetic pots based mechanical interface. Comparative eco-audit of technological path for CNC technology integration is required to optimize eco-innovation strategy to deliver sustainable remanufacturing. Such integrated platform of machine tool remanufacturing based on both emerged lower cost CNC technology adoption and capabilities of institutes of technology where the hybrid labor-student remanufacturing environment can be certain to deliver hybrid public-private services that is aimed to establish triple bottoms of economic, environmental and social sustainability.
