Abstract
A numerical control device includes: a program analyzing unit analyzing a transition of a moving velocity of a machining head and a transition of a supply amount of a material supplied to a beam-irradiation position based on a machining program; a movement distance calculating unit calculating a first distance based on a result of analysis performed by the program analyzing unit, the first distance being a length of a first movement section to a first position at which addition of the material to the workpiece is started, the first movement section being a section through which the machining head is moved while the head is accelerated; and a condition command generating unit generating a supply command to increase the supply amount of the material per hour from zero to a command value according to a machining condition while the machining head is moved through the first movement section.
