ABSTRACT:
A numerical control device for a machine tool switching two reference axes comprising switching timing determining means for determining a timing for switching the moving position definition on the basis of the first reference axis and the moving position definition on the basis of the second reference axis; and reference axis switching means for switching, in response to the switching timing determining means, the moving position definition on the basis of the first reference axis and the moving position definition on the basis of the second reference axis.
