Abstract
A method and a device for the controlled withdrawal movement of a machining electrode in an erosion device wherein, in the case of a process malfunction, the machining electrode is moved backward along the previously traveled machining path (B) (first way of withdrawal) and along a withdrawal vector (RV) defined in relation to the machining path (B) (second way of withdrawal). In order to quickly eliminate the process malfunction and at the same time reduce the risk that the machining electrode will hit the work piece surfaces during the withdrawal movement, the machining electrode is moved backward simultaneously along both ways of withdrawal, and the direction of the withdrawal vector (RV) at each point is adapted to the previously traveled machining path (B).
