Systems and methods are described for beneficially influencing the surface morphology of conductive materials using electrochemistry. The systems and methods for beneficially influencing the surface morphology of conductive materials use a bimodal process in which a first current type (AC or DC) is applied to an electrolyte between an electrode and a workpiece, followed by a second current type that is different from the first current type used. The bimodal process can be repeated one or more times.

Methods and systems of electrochemically machining a workpiece are provided. The method can include applying two or more electric potentials to a tool electrode comprising an array of two or more individual electrodes to generate two or more electric fields between the tool electrode and a workpiece opposite the tool electrode, wherein each of the two or more electric fields is generated by one of the array of two or more individual electrodes.
