Abstract
A tap machining method includes: forming a female thread by cutting while synchronizing a rotation phase of a main spindle with positions of a workpiece to be machined by the tap and the main spindle in a rotation axis direction of the main spindle, the main spindle rotating while holding a tap with a tool holder mounted on a distal end portion; and adding or subtracting an angle amount of torsional deformation of the tap generated according to a cutting speed to or from the rotation phase of the main spindle during the synchronization.
