![]() ![]() Regular readers of the COMSOL Blog may recall that there are many electrochemical processes that allow precise control over the manufacture of metal objects and surfaces: for example, electroplating in which a substrate is made to act as a cathode so that a thin layer of metal can be electrodeposited on the substrate surface. However, such a method, pulsed electrochemical machining (PECM), was the focus of a detailed investigation using numerical modeling presented at the COMSOL Conference 2016 Munich. The promise of a contactless method to machine surfaces with submillimeter precision and a clean surface, on metals of almost any hardness, might seem too good to be true. Precision machining and quality of surface finish are major concerns for manufacturers of metal parts.
