Electropolishing and pulsed electrochemical machining (PECM) are similar but distinct processes. While they are both advanced manufacturing processes utilizing electrochemistry, electropolishing is largely limited to surface finishing, while electrochemical machining can create more precise geometries with high repeatability.

An ultrahigh voltage is frequently required in electrochemical jet machining (EJM) to produce extreme current densities (>900 A/cm 2 for this study) to achieve maximum dissolution rates. However, such a high electric field easily induces a cathodic discharge at the nozzle, and the generation mechanism and characteristics remain unexplored.
