1. , a kind of method that is used for monitoring the machining of electroerosion assembly (100), this assembly (100) has power supply (20) and crosses at least one electrode 10 that gap (12) is provided with from workpiece (14), power supply by applying electrical potential difference Δ

  • V between electrode and workpiece in a plurality of pulse turn-on cycles is to this electrode power supply, and described method comprises;

    Fixed time at the only about half of at least pulsewidth Δ

    τ

    of voltage waveform postpones t dMeasure the voltage at a some place on the voltage waveform of electroerosion assembly afterwards;

    For a plurality of pulse duplicate measurements of voltage waveform, to obtain a plurality of voltages, the point in corresponding each pulse of each voltage;

    Average these voltages are to obtain average voltage;

    Compare average voltage and at least one threshold voltage V ThTo judge that whether machining is Guaranteed;

    If show that relatively this technology not Guaranteed, then produces at least one control signal, this at least one control signal is set to regulate at least one operational factor of power supply;

    AndIf produced control signal, then at least one control signal is imposed on power supply.
