Abstract Scope |
As-built metal Additive Manufacturing (AM) parts require secondary processing in most applications to improve surface finish and mechanical strength. Mass finishing technologies use abrasive media to deburr bulk parts to improve surface finish. Fixtureless MF method such as Centrifugal Disc Finishing (CDF) is an effective and economical surface improvement method for additively manufactured metal parts. However, effects of different build orientations and AM processes on the wear behaviors between abrasive media and AM surfaces are still unclear. This study investigates the wear behavior of Laser Powder Bed Fusion (L-PBF) and Electron Beam Powder Bed Fusion (EB-PBF) fabricated Ti6Al4V parts by post processing with CDF. Both AM orientation-based surface finish and wear behavior are evaluated to gain new insights into the key mechanism of AM mass finishing. In addition, findings from this study could offer optimal build orientation and mass finishing for surface improvement. |
