Abstract
An NC device, which is a numerical control device, includes: a program analyzing unit that analyzes a machining program to obtain a movement path along which to move a supply position of a material on a workpiece; a storage temperature extracting unit that extracts, from data on surface temperature of the workpiece, storage temperature in an area including the movement path on the workpiece; a layering volume calculating unit that calculates a volume of a layer forming an object on the basis of a relation between the storage temperature and a volume of the material that solidifies at the storage temperature in a given time; and a layering shape changing unit that changes a shape of the layer on the basis of the volume of the layer.
