Title (EN) ON-MACHINE MEASURING METHOD AND CONTROL DEVICE OF MACHINE TOOL
(FR) PROCÉDÉ DE MESURE SUR MACHINE ET DISPOSITIF DE COMMANDE DE MACHINE-OUTIL
(JA) 工作機械の機上測定方法および制御装置
Abstract:
(EN) When measuring the position of a workpiece (W) fixed to a table (16) of a machine tool: rotary feed axes (A, C) of the machine tool are pivoted such that an upper surface of the table (16) faces in the direction of a line of sight (O0) of a camera (120), and an image of the workpiece (W) is captured; the rotary feed axes (A, C) are pivoted such that a side surface of the table (16) faces in the direction of the line of sight (O0) of an image capturing device, and an image of the workpiece (W) is captured; and the position of the workpiece (W) is measured on the machine tool on the basis of the captured images.
(FR) La présente invention concerne un procédé de mesure de la position d'une pièce (W) fixée à une table (16) d'une machine-outil, consistant : à faire pivoter les axes d'alimentation rotatifs (A, C) de la machine-outil de sorte qu'une surface supérieure de la table (16) soit orientée dans la direction de la ligne de visée (O0) d'une caméra (120), et à capturer une image de la pièce (W) ; à faire pivoter les axes d'alimentation rotatifs (A, C) de sorte qu'une surface latérale de la table (16) soit orientée dans la direction de la ligne de visée (O0) d'un dispositif de capture d'image, et à capturer une image de la pièce (W) ; et à mesurer la position de la pièce (W) sur la machine-outil sur la base des images capturées.
(JA) 工作機械のテーブル(16)に固定されたワーク(W)の位置を測定する際、工作機械の回転送り軸(A、C)を回動してテーブル(16)の上面をカメラ(120)の視線(OO)の方向に向けてワーク(W)を撮像し、回転送り軸(A、C)を回動してテーブル(16)の側面を撮像装置の視線(OO)の方向に向けてワーク(W)を撮像し、撮像した画像に基づきワーク(W)の位置を工作機械の機上で測定するようにした。
