摘要：Aims: Accelerated developments of CNC machines will let huge amount of milling machines to beout of date. To cope with such problem conventional milling machines can be upgrading by usingwhat is called emerged technology which is of attributes of: The same performance of new machines can be obtained in like-new form remanufacturedCNC milling machine. Economic feasibility can be certain. Various purposes can be satisfied include education, training and industry. Efficiency and accuracy requirements can be within limits of customer expectations. Sustainability assessment approach that contains feasibilities of technology, economic andenvironment modeling for conventional milling into CNC machine tool remanufacturing.Study Design: Literature is surveyed for specifying criteria of feasibilities of technology, economicand environment modeling. Mathematical sub-models are confirmed based on comparativeliterature based analysis to be used to find the values of indexes of assessment feasibilities withininsights of experience based analysis. Feasibilities which are selected to conduct sustainabilityassessment of remanufacturing processes include sub-feasibility of:1- Easy of disassembly sub-feasibility: As low as the time of disassembly, the higher theindex of criterion and the easier disassembly.2- Sub-feasibility of cleaning: As easy as the cleaning process, the lower the index value ofcriterion.3- Sub-feasibility of inspection and sorting: As low as the time of inspection and sorting, thehigher the index of criterion and the easier inspection and sorting.4- Sub-feasibility of upgradability: As high as the accuracy of remanufactured milling intoCNC machine tool, the higher the index value of criterion.5- Easy of reassembly sub-feasibility: As low as the time of reassembly, the higher the indexvalue of criterion and the easier reassembly.6- Sub-feasibility of tack-back cost: It is net price of conventional milling machine to beremanufactured into CNC machine tool.7- Sub-feasibility of remanufacturing process cost of: It is expense of purchasing replacingparts, material resource consumption and electrical energy consumption.8- Sub-feasibility of overhead cost: Operating expense to keep continues machine toolremanufacturing business.9- Material saving sub-feasibility: It is the mass of reused components.10- Energy saving sub-feasibility: It is the ratio of consumed energy to embodied energy as aresult of preventing manufacturing processes by remanufacturing.11- Pollution reduction sub-feasibility: It is embodied emissions reduction as a result ofpreventing manufacturing processes by remanufacturing.Place and Duration of Study: Middle Technical University, Institute of Technology-Baghdad,Mechanical Techniques Department, between February 2020 and July 2020.Methodology: Study methodology includes the following outlines:- Literature survey. Comparative literature based assessment application. Experience based analysis application. Isolation of indices Weighting of indexes Sustainability Index calculationResults: Comparative literature based analysis and experience based analysis are used to find theindexes of sub-feasibilities where assessment feasibilities can be calculated through multiplication ofindex weight by weight of importance. Three evaluation results are calculated to assess theperformance of sustainability where index value of (70%) can refer to that conventional millingmachine is of high innovative contribution potentials to deliver sustainable solution of CNC machinetool remanufacturing.Conclusion: Technology, Economic and environment are of good evaluation indexes andconventional milling into CNC machine tool remanufacturing is directed toward sustainability.
