Description
Hao Li and co-authors model magnetic polishing for rough internal channels in printed metal parts in a 2026 study. Channels made by laser melting carry surface flaws that hurt flow and fatigue life, and tools cannot reach inside easily. Magnetic abrasive finishing adapts to such shapes, so its removal physics were formalized.
Two wear modes, rolling and sliding, were modeled with rough-surface contact theory and correction factors. Experiments on printed aluminum channels in a combined magnetic field setup checked the math. The process cut defects and roughness as predicted, with gaps blamed on model idealization and uneven fields. Manufacturing engineers gain a systematic theory for a finishing method that industry uses by feel. Predictable removal brings printed cooling channels closer to flight and medical standards.
