چکیده
Internal surfaces generated by additive manufacturing (AM) are finding their wide applications in aerospace, automobile, and medical industries. Nevertheless, the poor surface quality resulting from intrinsic melting solidification process of laser powder bed fusion (L-PBF) is still a common issue for full functionality fabricated components. Though conventional abrasive-based chemical-based finishing methods have been recently deployed to improve finish AM-ed internal surfaces, they may limitations unresolved issues such as low material removal rate, uneven chemical hazards. In this study, magnetically driven (MDIF) with magnetic polishing tools developed AISI 316L stainless steel tube printed selective (SLM), one most typical L-PBF processes. Results demonstrate that roughness single-point section-polishing experiments can be reduced as-printed level 11.599 μm Ra 0.385 0.808 Ra, respectively, within tens minutes time. Benchmarking abrasive (MAF) shows MDIF outperforms MAF terms both final efficiency. Besides, model based on Abbott-Firestone curve predict mass SLM-ed workpiece average predicting errors only 7.9% 13.4% experiment experiment, respectively. This paper provides an efficient alternative existing addressing surfaces.
