摘要： A wire electric discharge machining program is analyzed and a target shape for a workpiece is created. Multiple amounts of adjustment by which the amount of wire radius compensation for a wire electrode is adjusted are set. One or more desired ones are selected from the amounts of adjustment, and the amount of wire radius compensation is calculated by adding the selected amount(s) of adjustment to the amount of wire radius compensation. A machining route which is offset from the created target shape by the calculated amount of wire radius compensation is created.

摘要： A method for monitoring machining in an electroerosion assembly having a power supply and an electrode arranged across a gap from a workpiece, includes measuring a voltage at a point in a voltage waveform after a time delay td of one half of a pulse width of the voltage waveform. The measurements are repeated for multiple pulses of the voltage waveform to obtain multiple voltages, each of the voltages corresponding to a point in respective pulses. The voltages are averaged to obtain an average voltage, which is compared with at least one threshold voltage, to determine whether the machining is in control. A control signal is generated if the comparison indicates that the process is not in control, the control signal being configured to regulate an operating parameter of the power supply, and the control signal is supplied to the power supply, if generated.
