摘要：Aims: Remanufacturability Index (RI) was calculated to indicate the ability of remanufacturing conventional shaping into CNC machine tool through multi-criteria assessment methodology. Place and Duration of Study: Middle Technical University, Institute of Technology-Baghdad, Mechanical Techniques School, between 2021/2022. Methodology: Conventional shaping machines which are remanufactured-upgraded into CNC machine tools were analyzed to classify a group of seven remanufacturing-upgrading alternatives. Multi-criteria were defined include cost, time, accuracy and complex shape, reliability, processing range and efficiency and ergonomic. Weighting of importance of criteria and performance of alternatives were conducted by applying comparative literature analysis and machine tool remanufacturing experience analysis of mechanical structure of remanufactured-upgraded conventional shaping into CNC machine tool as well as alternatives performances scoring. Results: As many as the number of automated axes, as high as the Remanufacturability Index (RI) which is dedicated to remanufactured-upgraded conventional shaping into 2-axis to 5-axis CNC machine tool. Conclusion: Remanufactured-upgrading conventional shaping into CNC machine tool is of high remanufacturing potentials that satisfy conditions of technical, economic and environmental feasibilities.
