The present invention relates to a turning method for performing turning on a workpiece that rotates about a rotation axis. The turning method includes: driving a first movement apparatus for moving a turning tool in a radial direction of the rotation axis to locate a cutting edge of the turning tool at a first radial position in the radial direction; driving a second movement apparatus for moving the turning tool in parallel with the rotation axis, performing turning on the workpiece, and then moving the turning tool in a reverse direction to retract the turning tool from the workpiece; measuring a processed dimension of the workpiece, and calculating an error between the processed dimension that has been measured and a target dimension; driving a third movement apparatus for moving the turning tool relative to the first movement apparatus in the radial direction of the rotation axis to locate the cutting edge of the turning tool at a second radial position so as to correct the error; and driving the second movement apparatus to move the turning tool in parallel with the rotation axis, and performing turning on the workpiece.
