Abstract

L’invention concerne un procédé de détection de fin de perçage par électroérosion d’un trou dans une pièce en matériau électro-conducteur, le procédé comprenant les étapes consistant en : le perçage (S100) par électroérosion d’au moins un trou dans la pièce,au cours du perçage par électroérosion, l’acquisition (S200), au moyen d’un capteur de vibrations, de mesures représentatives des vibrations émises lors du perçage par électroérosion, et le traitement (S300) des mesures acquises, etl’arrêt du perçage (S400) par électroérosion en fonction des mesures traitées. Figure pour l'abrégé : Figure 4The invention relates to a method for detecting the end of drilling by electroerosion of a hole in a part made of electro-conductive material, the method comprising the steps consisting of: drilling (S100) by electroerosion of at least one hole in the part, during drilling by electroerosion, the acquisition (S200), by means of a vibration sensor, of measurements representative of the vibrations emitted during drilling by electroerosion, and the processing (S300) of the acquired measurements, and stopping drilling (S400) by electroerosion according to the processed measurements.
