<p>In a method for electrochemical machining the working distance (dw) is set by contacting the workpiece (2) with the electrode (3) (phase I), increasing the distance between the workpiece (2) and the electrode (3) by a first distance (d1) (phases II-III), detecting whether the contact between the electrode (3) and the workpiece (2) is broken (phase IV), and further increasing the distance between the workpiece (2) and the electrode (3) by a second distance (d2). Owing to this method very small working distances can be set with a limited risk of short-circuiting and flash-over.</p> |
