Abstract
A numerical control device used for a machine tool and configured to move a machining tool and a workpiece in the same direction on parallel respective drive shafts based on a machining program and control a relative positional relationship between the machining tool and the workpiece during the motion in the same direction, at least one of motion instructions for the machining tool and the workpiece being an instruction whose instruction value varies arbitrarily with time elapsed, includes: a machining program analysis unit that acquires the motion instructions for the machining tool and the workpiece from the machining program; a motion instruction generation unit that generates machining tool motion instruction data on the machining tool and workpiece motion instruction data on the workpiece based on the motion instructions; and an interpolation unit that generates machining tool interpolation data based on the machining tool motion instruction data and generates workpiece interpolation data based on the workpiece motion instruction data.
