Abstract: An NC device for correcting a blade edge position at a time of a turning tool being mounted on a tool main spindle in a machine tool, comprising: first acquisition part for acquiring an inclination amount of a clamp surface of the tool main spindle; second acquisition part for acquiring a tool shaft rotation phase angle; third acquisition part for acquiring a protrusion amount in which the blade edge is protruded from the clamp surface of the tool main spindle; and first correction arithmetic processing part for arithmetically processing a deviation amount of the position of the blade edge that is generated between a reference position and the shaft rotation phase angle obtained by the second acquisition part due to the inclination amount of the tool clamp surface obtained by the first acquisition part and the protrusion amount obtained by the third acquisition part.
