This paper will discuss recent developments toward the demonstration of electrochemical processing conditions and tooling that enables complex components produced by additive manufacturing approaches to be finished. Unlike conventional machining processes, where surfaces are accessible, one benefit of this approach is that it enables parts to be built with internal channels that maybe inaccessible to conventional process. Furthermore, the paper presents a pulse/pulse reverse electrofinishing approach to polish various material groups including titanium alloys, nickel alloys, and stainless steels alloys. This approach enables improved process control and efficiency, while utilizing low cost, scalable, water-based electrolytes. Specifically, in this talk we will discuss techniques in electrofinishing AM / HIPped parts and the design of tooling that enables complex components / passages to be finished. Finally, we plan to discuss the results of the spin test that will be performed on the electrochemically finished Ti64 AM shrouded impellers.
