Abstract: A method of and apparatus for controlling electric discharge machining in which a machining gap formed between a tool electrode and a workpiece is maintained at an essentially constant size based on a reference servo-feed voltage, and in which a jump action, for moving a tool electrode up and away from a workpiece, and returning it to a position close to the workpiece is controlled. The reference servo-feed voltage and conditions for jump action are optimally set to required values during machining according to the discharge stability. The discharge stability is obtained by comparing the actual values of characteristics required for specifying gap condition, e.g., waiting time for a discharge to occur, the voltage during the waiting time, discharge frequency, to the corresponding theoretical values. The theoretical values are calculated in part according to given machining conditions. Therefore, even when machining conditions change as machining progresses, jump action and servo-feed action are properly controlled.

Abstract: An electrochemical fine processing apparatus for electrochemically performing an adding processing and a removing processing of a substance such as a metal or a polymer in a solution in order to produce a structure having a high aspect ratio. Removing electrodes for applying an electric potential opposite to that applied to an addition electrode are disposed around the addition electrode, whereby an excess portion of metal or polymer film pattern can be scraped electrochemically. In addition, alternate electric potential pulses are applied successively to the addition electrode and then to the removing electrodes. It becomes possible to form on the support a structure with sharp pattern edge portions and a high aspect ratio.
