Abstract
This work discloses the preliminary results of a feasibility study of a novel setup and procedure for electropolishing internal channels of additively manufactured components. A specially designed and printed polymeric cover was assembled with a flexible stainless steel 316 wire to facilitate electropolishing of internal channels with various curvatures. Experimental studies were conducted to assess the feasibility of the process. The presence of curvatures was found to influence the formation and removal of conductive solid reaction products, thus affecting the electropolishing performance accordingly. A maximum surface roughness Sa reduction from 10.86 ± 0.50 μm to 1.44 ± 0.46 μm was obtained for straight channels after electropolishing for 20 min, while less efficient surface smoothening performance was observed on curved channels. Following that, a numerical simulation was conducted for optimization of wire covers, and the performance of three designs were analyzed and compared. While challenges need to be solved for improving the electropolishing performance and reducing the limit of the channel size that can be electropolished, the methods show significant potential on electropolishing curved internal channels, which can be further used in industrial-scale applications.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
