Abstract:
1. A method for the electrochemical machining of at least one workpiece, comprising at least the following steps: a) setting a first current density during a first phase in an electrolyte, b) retaining the first current density during a second phase, directly following the first phase, c) increasing the first current density during a third phase, directly following the second phase, from the first current density to a second current density that is at least 30% higher in comparison with the first current density, and d) reducing the second current density during a fourth phase, following the third phase, to a maximum of 1% of the second current density within a maximum of 100 microseconds, wherein a positive, non-zero current density is present within the electrolyte from the first phase through the third phase.
