Abstract

The invention relates to a method and a device for machining a work piece by means of electrochemical material removal, comprising a tool electrode that can be positioned at a distance from an electrically conductive work piece area that is to be machined and that is serving as work piece electrode, wherein voltage impulses are applied between the tool electrode and the work piece electrode and the corresponding progression of electrode current intensity is detected and used as criterion for electrode spacing. According to the invention, it is detected whether the progression of electrode current intensity shows an initial overshoot followed by an undershoot of the reference progression during a corresponding voltage impulse in relation to a reference progression (lr) having the same shape relative to the voltage impulse progression. The result is then considered as a criterion for electrode spacing. Alternatively, detection of initial overshooting can already be considered as a criterion for setpoint or minimal distance. The invention can be used in the electrochemical material removal techniques.
