DEVICE AND METHOD FOR MONITORING A PRODUCTION METHOD FOR THE PREPARATION OF A THROUGH DRILLING

摘要

The invention relates to a method for monitoring a production method for the preparation of a through drilling, in particular, by means of spark erosion, comprising the following steps: recording of actual values for the structure-borne noise generated during machining and determination of a breakthrough and/or a finishing of the through-hole by means of the recorded current values for structure-borne noise. The invention further relates to a device for monitoring a production method for the preparation of a through-hole.
