Remanufacturingability Modeling Approach on Remanufacturing Conventional Machine into CNC Machine Tool

Aims: Assess to find the most suitable remanufacturing portfolio alternatives to restore dovetail guide ways and saddles of machine tools.

Study Design: Comparative literature based analysis adoption to apply a series of assessments to find the remanufacturability of best restoration portfolio alternative where portfolios are developed by using scenario based analysis and results are optimized using remanufacturing experience based analysis.

Place and Duration of Study: Middle Technical University, Institute of Technology-Baghdad, Mechanical Techniques Department, between January 2020 and July 2020.

Methodology:

Literature survey aided remanufacturing assessment case studies elicitation.
Sample of published papers re-representation to highlight the findings of discussions and conclusions of these papers.
Graphical representation of results is also applied.
Study of published papers sample allows isolation of criteria, weighting of criteria, weighting of alternatives, global weights calculation and alternatives ranking of remanufacturing portfolio alternatives to restore dovetail guides ways and saddles of machine tools.
Conclusion: Series of different assessments with different groups of criteria lead to propose hypotheses to be highlighted to continue application of comparative literature based assessment, proposed hypotheses include:

As much as uniform is the Rank-Global weights curve of portfolio alternatives the more consistent is the assessment matrix.
Technical viability of remanufacturing portfolio will lead to economic and environmental viabilities.
Economic and environmental viabilities necessarily can certain remanufacturability and will lead to social viability.
Technical, economic, environmental and social viabilities will lead to sustainability.
Integrated technical viability of a remanufacturing portfolio is an integration of derivatives of technical viabilities of processes consist the portfolio.
Comparative literature based assessment is a powerful tool under the mixture of remanufacturing experience based analysis and scenario based analysis.
Remanufacturability assessment, technical viability assessment and partial sustainability assessment can be mixed to develop comprehensive remanufacturing sustainability assessment.
Grinding-Mechanical Cladding is assembly based remanufacturing to improve machine tool remanufacturability and sustainability.
