Working Gap Analysis in Electrochemical Precision Machining of External Geometries with Ring Cathodes

Procedia CIRP, 2020
Abstract Pulsed electrochemical machining (PECM) with oscillating cathode is a non-conventional manufacturing technology to machine complex precision geometries independent from the mechanical properties of the workpiece material. PECM with oscillating cathode is an advanced development of conventional ECM by applying a pulsed electric current in ...
