Abstract: Methods and systems of electrochemically machining are provided. The methods may include applying a first potential to a tool electrode of an electrochemical machining system to generate a primary electric field. The electrochemical machining system may include a workpiece opposite the tool electrode, at least one bias electrode, and at least one fluid delivery channel within the at least one bias electrode. The method may further include applying at least one second potential to the at least one bias electrode. The method may further include delivering a charged electrolyte solution through the at least one fluid delivery channel into the electrolyte solution. Applying at least one second potential and the delivering the charged electrolyte solution generates at least one secondary electric field adjacent to the primary electric field and quenches at least one location of the primary electric field.

Abstract: Methods and systems of electrochemically machining a component are provided. The method may include applying two or more potentials to a tool electrode comprising an array of two or more individual electrodes to generate two or more electric fields in between the tool electrode and a workpiece opposite of 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.

Abstract: A method of operating an electrochemical machining system includes selectively performing an electrochemical machining process by an electrochemical machine of the electrochemical machining system in a macromachining mode or a micromachining mode by controlling a purity level of a machining liquid supplied to the electrochemical machine.
