Abstract: An optical correction is predictively performed based on a result of AI learning previously performed by use of learning data including measurement data. The optical compensation system is provided with wavefront correction optics, a sensor and a controller. The wavefront correction optics corrects a wavefront of light that passes through a given optical path. The sensor obtains environmental information in the optical path. The controller calculates, based on the environmental information, a predicted wavefront disturbance of the light that has passed through the optical path and controls the wavefront correction optics so as to cancel the predicted wavefront disturbance.

Abstract: In the process of cutting the outer circumference 10o of a hollow rotating shaft 10 by using a finishing turning tool 36, the position of the finishing turning tool 36 is adjusted in the direction orthogonal to the virtual reference shaft center VS so that the center position CPo of the outer circumference 10o of the hollow rotating shaft 10 is deviated from the virtual reference shaft center VS in the same direction as the direction of the deviation vector ?Di by an amount corresponding to the magnitude |?Di| of the deviation vector ?Di. This can reduce the unbalance to zero also in the middle of the shaft and sufficiently reduce runout of the hollow rotating shaft 10 even if the rotation speed of the hollow rotating shaft 10 increases. Accordingly, it is possible to further improve the reliability of the hollow rotating shaft 10 at high rotation speed.
