Title
(EN) TENSION INFORMATION ACQUISITION DEVICE, WIRE ELECTRICAL DISCHARGE MACHINE, AND TENSION INFORMATION ACQUISITION METHOD
(FR) DISPOSITIF D'ACQUISITION D'INFORMATIONS DE TENSION, MACHINE À DÉCHARGE ÉLECTRIQUE FILAIRE ET PROCÉDÉ D'ACQUISITION D'INFORMATIONS DE TENSION

Abstract
(EN) A tension information acquisition device (18) acquires tension (FT) of a wire electrode (12) and is provided with: a back tension adjustment unit (56) that makes the magnitude of back tension (FBT) of the wire electrode (12) zero; and an acquisition unit (58) that acquires tension information indicating the tension (FT) on the basis of a disturbance estimate value (VD) or output torque of a feed motor (42A) when the magnitude of the back tension (FBT) is zero.
(FR) Un dispositif d'acquisition d'informations de tension (18) acquiert une tension (FT) d'une électrode filaire (12) et comporte : une unité de réglage de tension de retour (56) qui rend nulle l'amplitude de tension de retour (FBT) de l'électrode filaire (12) ; et une unité d'acquisition (58) qui acquiert des informations de tension indiquant la tension (FT) sur la base d'une valeur d'estimation de perturbation (VD) ou d'un couple de sortie d'un moteur d'alimentation (42A) lorsque l'amplitude de la tension de retour (FBT) est nulle.
(JA) ワイヤ電極(12)の張力(F)を取得する張力情報取得装置(18)であって、前記ワイヤ電極(12)のバックテンション(FBT)の大きさをゼロにするバックテンション調整部(56)と、バックテンション(FBT)の大きさがゼロのときの送りモータ(42A)の外乱推定値(V)または出力トルクに基づいて前記張力(F)を示す張力情報を取得する取得部(58)と、を備える。
