In a numerically controlled machine tool which has a linear feed axis and a rotational feed axis and in which a main spindle and a table are movable relative to each other, a position error and an attitude error produced by an operation of a linear feed axis and a rotational feed axis are measured at a plurality of measurement points set within a movable range of the linear feed axis and the rotational feed axis, and the position error and the attitude error thus measured are stored as an error map in correspondence to a position of the linear feed axis and a rotation angle of the rotational feed axis.
L'invention concerne une machine-outil à commande numérique qui comporte une barre de chariotage linéaire et une barre de chariotage rotative dans laquelle un arbre principal et une table peuvent se déplacer l'un par rapport à l'autre, dans laquelle machine-outil les erreurs de position et d'attitude provoquées par les actions de la barre de chariotage linéaire et de la barre de chariotage rotative sont mesurées en plusieurs points de mesure définis à l'intérieur des plages de déplacement de la barre de chariotage linéaire et de la barre de chariotage rotative, puis les erreurs de sa position et de son attitude sont stockées sous la forme d'une carte d'erreurs correspondant à la position de la barre de chariotage linéaire et à l'angle de rotation de la barre de chariotage rotative.
