Abstract: front page image
(EN)The present invention provides a method and a device for real time position correction by the deformation of a ball screw of a machine tool, wherein force applied to a ball screw is detected by using torque data which is applied to the servo motor of a conveying shaft when conveying or machining of a machine tool is performed, an error of a pitch that the ball screw deforms is calculated in consideration of the detected force and the mechanical strength of the conveying shaft including the ball screw, and the calculated error of the pitch is corrected by data which is corrected on a stored pitch error table such that the precision of the conveying and machining is improved. According to the present invention, the positional error of the conveying shaft, which is generated when conveying and machining is performed, may be corrected in real time.
(FR)La présente invention porte sur un procédé et un dispositif pour la correction de position en temps réel par la déformation d'une vis à billes d'une machine-outil, dans lesquels une force appliquée à la vis à billes est détectée à l'aide de données de couple qui sont appliquées au servomoteur d'un arbre de transport lorsqu'un transport ou un usinage d'une machine-outil est exécuté, une erreur d'un pas que la vis à billes déforme est calculée en tenant compte de la force détectée et de la résistance mécanique de l'arbre de transport qui comprend la vis à billes, et l'erreur calculée du pas est corrigée par des données qui sont corrigées sur une table d'erreur de pas stockée en mémoire, de sorte que la précision du transport et de l'usinage est améliorée. Selon la présente invention, l'erreur de position de l'arbre de transport, qui est produite lorsqu'un transport et un usinage sont exécutés, peut être corrigée en temps réel.
(KO)본 발명은 공작기계의 이송 및 가공시 이송축의 서보모터에 작용하는 토크데이터를 이용하여 볼스크류에 가해지는 힘을 검출하고 검출된 힘과 볼스크류를 포함하는 이송축의 기계적 강성을 고려하여 볼스크류가 변형하는 피치의 오차를 계산하며 계산한 피치의 오차를 기 저장된 피치 오차 테이블에 수정하여 수정된 데이터만큼 보정함으로써 이송 및 가공의 정밀도를 향상시킨 공작기계의 볼스크류 변형에 의한 실시간 위치 보정 방법 및 장치를 제공한다. 이러한 본 발명에 따르면 이송 및 가공시 발생하는 이송축의 위치 오차를 실시간으로 보정하는 것이 가능하다.
