Abstract
A numerical control device is the numerical control device that controls a machine tool including a plurality of spindles that each rotate a tool opposed to a workpiece around a tool axis relative to the workpiece and a feed shaft that performs a feed operation such that a plurality of the tools relatively move closer to a plurality of the workpieces, and the numerical control device includes an associated-synchronous-tapping unit that associates, according to an associated-synchronous-tapping command, rotation and feed of a spindle on an associated side among the spindles with rotation and feed of a spindle on a reference side among the spindles and simultaneously performs synchronous tapping with the tools.
