    • 专利摘要:
    A process and apparatus for controlling the retraction of the electrode tool of an EDM machine such as to maintain the material removal rate to a value approaching the maximum theoretical value. The control system comprises monitoring the machining rate for providing an average value of the material removal rate during at least a time interval corresponding to a single retraction period of the electrode, and varying the frequency of subsequent retractions of the electrode as a function of that average value such as to consistently maintain a material removal rate which is self-adaptive and tends to reach a maximum theoretical value.

    The invention relates to electroplating methods of manufacturing and, in general, relates to a method of electron-processing with cyclic mixing and p, electrodes.
    The purpose of the invention is to produce: 1 processing.
