ELECTROCHEMICAL MACHINING EMPLOYING ELECTRICAL VOLTAGE PULSES TO DRIVE REDUCTION AND OXIDATION REACTIONS

摘要

Electrochemical machining of parts employs electric or voltage pulses in which current flows in a first direction and a second direction opposite from the first direction. The cathodic/anodic pulses switch between bulk machining and oxide removal pushing bulk material removal into a homogenous regime to obtain a smooth surface finish and appropriate form control during the electrochemical machining process compared to electrochemical machining employing an electric or voltage potential in which current flows in only one direction.
