Abstract
(DE)
Es wird ein Verfahren zur Qualitätsprüfung eines Werkstücks (1) vorgeschlagen, bei welchem das Werkstück (1) zu einer Schwingung angeregt (8), wenigstens ein Parameter der Schwingung gemessen (18) und das Werkstück für gut befunden wird, wenn der Parameter innerhalb eines vorgegebenen Rahmens liegt.
(EN)
The invention relates to a method for the quality control of a work piece (1). According to said method, said work piece (1) is incited to vibrate (8), at least one vibration-related parameter is measured (18) and the work piece is approved of if said parameter is within a predetermined range.
(FR)
L'invention concerne un procédé de contrôle qualité d'une pièce à usiner (1). Ce procédé consiste à exciter (8) la pièce à usiner (1) pour la soumettre à des vibrations et à mesurer (18) au moins un paramètre de vibration. La pièce à usiner est qualifiée de bonne lorsque le paramètre se situe dans des limites prédéterminées.
