ABSTRACT:
An electrode return control system for an electric spark machine includes a first control mode in which, when a short-circuit condition occurs, an electrode is moved away from its position in a workpiece along a path over which the electrode was advanced for machining, and a second mode in which an object point to which the electrode is to be moved directly upon the occurrence of a short-circuit condition is updated with the machining progress.
