Method for machining workpieces
First Claim
1. A method for machining workpieces, comprising providing a machining electrode which is guided at a specified operating distance to a workpiece, providing an electrolyte between the workpiece and the machining electrode, providing an operating current flowing between the machining electrode and the workpiece, which operating current results from an operating voltage (UA), which is produced at the machining electrode in relation to the workpiece, which workpiece is connected to ground, the operating voltage (UA) being applied in such a way that the operating current is a DC current or a pulsed DC current, superimposing a measuring voltage (UM) on the operating voltage (UA), detecting a measuring current resulting from the superimposing of the measuring voltage (UM), determining a distance between the machining electrode and the workpiece from a relationship between the measuring voltage (UM) and the measuring current.

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 (UA), 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 (UA) 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 (UM) is superimposed on the operating voltage (UA) for producing the operating current. The measuring current resulting because of the application of the measuring voltage (UM) is detected and the distance between the machining electrode and the workpiece is concluded from the relationship between the measuring voltage (UM) and the measuring current.
