Abstract
According to an exemplary embodiment, an industrial machine includes: a movement mechanism configured to move along a specific axis direction; a controller configured to control the movement mechanism; and an angle detector configured to detect an angle of the movement mechanism about an axis perpendicular to the specific axis direction. The controller comprises: an angular error acquisition section configured to acquire angular errors of the movement mechanism for respective positions of the movement mechanism based on the angle detected when the movement mechanism is moved; a parameter generator configured to generate respective straightness correction parameters for correcting straightness errors of the movement mechanism in the specific axis direction by integrating the angular errors at the respective positions of the movement mechanism; and a correction section configured to correct movement errors of the movement mechanism based on the straightness correction parameters.
