PROBLEM TO BE SOLVED: To provide an accuracy measuring method, an error correction method for a numerically controlled machine tool and a numerically controlled machine tool with an error correcting function, which can eliminate the influence of a deflection of a test bar due to the rotating operation of a rotation feed shaft and improve the accuracy of a machine.;SOLUTION: In the accuracy measuring method for measuring the accuracy of the machine, a reference ball is attached to the main spindle or the table of the machine to measure the amount of deflection of the support shaft of the reference ball. A correction value is calculated on the basis of the measured amount of deflection of the support shaft of the reference ball and the correction value is added to the measured value to measure the accuracy of the machine.;COPYRIGHT: (C)2010,JPO&INPIT
