Title
(EN) MACHINING SYSTEM, AND METAL MEMBER MANUFACTURING METHOD
(FR) SYSTÈME D'USINAGE ET PROCÉDÉ DE FABRICATION D'ÉLÉMENT MÉTALLIQUE
(JA) 加工システム、及び金属部材の製造方法
Abstract
(EN)
A machining system comprising: a tool that machines a workpiece comprising a metal member; a motor that rotates the workpiece or the tool; a control unit that controls the motor; and a measurement unit that acquires the electric charge of the motor, wherein the control unit changes the rotational speed of the motor on the basis of the difference between a first electric charge and a second electric charge. The first electric charge is the electric charge acquired by the measurement unit while the motor is rotating and before the workpiece is machined, and the second electric charge is the electric charge acquired by the measurement unit while the workpiece is being machined.
(FR)
L'invention concerne un système d'usinage comprenant : un outil qui usine une pièce à travailler comprenant un élément métallique ; un moteur qui fait tourner la pièce à travailler ou l'outil ; une unité de commande qui commande le moteur ; et une unité de mesure qui acquiert la charge électrique du moteur, l'unité de commande modifiant la vitesse de rotation du moteur sur la base de la différence entre une première charge électrique et une seconde charge électrique. La première charge électrique est la charge électrique acquise par l'unité de mesure tandis que le moteur est en rotation et avant que la pièce à travailler ne soit usinée, et la seconde charge électrique est la charge électrique acquise par l'unité de mesure tandis que la pièce à travailler est usinée.
(JA)
金属部材からなる被削物を加工する工具と、前記被削物又は前記工具を回転させるモータと、前記モータを制御する制御部と、前記モータの電気量を取得する測定部と、を備え、前記制御部は、第一電気量と第二電気量との差分に基づいて、前記モータの回転数を変え、前記第一電気量は、前記モータの回転中かつ前記被削物の加工前に前記測定部で取得された電気量であり、前記第二電気量は、前記被削物の加工中に前記測定部で取得された電気量である、加工システム。
