Abstract
The invention relates to a method machining a particularly planar component by means of electrochemical machining, wherein the component has internal stresses resulting particularly from preceding manufacturing steps. In a first step a) of the method, the component to be machined is provided. Subsequently, in step b), at least two tools are provided in the form of electrodes and, in step c), an electrolyte is provided between the component and the at least two electrodes. In step d), a positive voltage is applied to the component and a negative voltage is applied to the at least two electrodes. Thus, in step e), by moving the at least two electrodes along their respective movement paths with respect to the component, electrochemical machining can take place; in the process, the gap between each electrode and the component is flushed with the electrolyte at least intermittently.
