Title (EN) METHOD AND DEVICE FOR SUPPRESSING CHATTERING OF WORK MACHINE
(FR) PROCÉDÉ ET DISPOSITIF POUR SUPPRIMER LE BROUTEMENT D'UNE MACHINE DE TRAVAIL
(JA) 作業機械のびびり抑制方法及び装置
Abstract:
(EN) Disclosed is a method for suppressing chattering of a work machine comprising a step (S1) of detecting vibration occurring when the rotation of a bit or a work (W) is started, a step (S3) of determining whether or not the vibration detected after the time when the rotation is started exceeds a threshold, a step (S4) of analyzing the vibration by Fourier series expansion when the vibration is determined to have exceeded the threshold, and a step (S21) of adjusting the rotational speed of the spindle.
(FR) L'invention concerne un procédé pour supprimer le broutement d'une machine de travail comprenant une étape (S1) de détection des vibrations survenant quand la rotation d'un foret ou d'une pièce à travailler (W) commence, une étape (S3) visant à déterminer si la vibration détectée dépasse ou non un seuil après le début de la rotation, une étape (S4) d'analyse de la vibration par extension de la série de Fourier quand il est déterminé que la vibration a dépassé le seuil, et une étape (S21) d'ajustement de la vitesse de rotation du mandrin.
(JA) 作業機械のびびり抑制方法は、バイト又はワークWの回転が開始される際に発生する振動を検出する工程(S1)と、前記回転開始時から検出される前記振動が閾値を超えたか否かを判断する工程(S3)と、前記振動が前記閾値を越えたと判断された際、前記振動をフーリエ級数展開により解析し(S4)、主軸の回転数を調整する工程(S21)とを有している。
