Abstract
A method for machining workpieces provides a machining electrode, which is guided at a specific distance to the workpiece. An electrolyte is provided between the workpiece and the machining electrode, through which an operating current flows between the machining electrode and the workpiece. The operating current results from an operating voltage (U), which is produced at the machining electrode, the workpiece being connected to ground. To perform the machining procedure, the distance between the machining electrode and the workpiece is regulated and the operating voltage (U) is determined in such a way that the resulting operating current is a DC current or a pulsed DC current—i.e., the operating voltage is a DC voltage of fixed or specific dimension. A measuring voltage (U) is superimposed on the operating voltage (U) for producing the operating current. The measuring current resulting because of the application of the measuring voltage (U) is detected and the distance between the machining electrode and the workpiece is concluded from the relationship between the measuring voltage (U) and the measuring current.
