Abstract

Combined additive and subtractive (i.e. CNC machining) technologies is demonstrated as a solution to inherent problems of additive manufacturing, such as poor surface quality, limited dimensional accuracy, and lengthy production time when compared to CNC machining. Researchers already identified that combining additive and subtractive manufacturing would be promising for remanufacturing application (Le, V.T, H. Paris, and G. Mandil, 2017). Remanufacturing sector has substantial promises towards sustainable future. In this study, our goal is to identify and categorize a list of applicable sustainable performance indicators (PI) to use during process planning to combine additive and subtractive manufacturing. Finally, the efficacy of the proposed approach is demonstrated through a case study. This study will assist product designers and (re)manufacturers to choose alternatives to model their combined manufacturing processes towards sustainability.
