Abstract:
A method of electochemically machining a workpiece by means of an electrode, comprising the steps ofbringing the workpiece and the electrode into contact with one another,setting a working distance (dw) between the electrode and the workpiece while keeping a gap between the workpiece and the electrode filled with an electrolyte, andpassing an operating current through the electrolyte in the gap via the electrode and the workpiece in order to machine the workpiece,wherein the working distance (dw) is set byincreasing, initially from a situation of contact between the electrode and the workpiece, a distance (d) between the electrode and the workpiece by a first distance (d1) to form an increased distance,detecting whether the contact between the electrode and the workpiece is broken, andincreasing the increased distance between the workpiece and the electrode by a second distance (d2) if the detecting shows that the contact between the electrode and the workpiece is broken.
