| Summary: | The present invention is generally related to a drilling electric discharge machine, and more particularly, to an automatic breakthrough detection device for drilling electric discharge machine.
An automatic breakthrough detection device for drilling electric discharge machine is provided. The automatic breakthrough detection device utilizing the facts of the variations of high frequency spectrum components of the provided discharge voltage and the variation of servo-feed-rate of the electrode as drilling discharge. The device includes a high frequency spectrum detecting analyzer to produce digital logic determining signals and a breakthrough judging logic device to judge the breakthrough by the electrode on the workpiece. Accordingly, the drilling electric discharge machine automatically adjusts the discharge parameters and the electrode withdrawals from the drilled hole and continues the next drilling hole on the workpiece. The present invention also provides a method of the same. |
