ABSTRACT:
A numerical control device for driving at least two mechanical axes which are not orthogonal to each other, including an inclination ratio setting device for setting an inclination ratio (angle) between actual mechanical axes corresponding to axes of a pseudo-set orthogonal coordinate system; an orthogonal axis direction mechanical error storage device for storing a mechanical error measured in the axial direction of the virtual orthogonal coordinate system; and an error converting device for obtaining a mechanical error in the actual mechanical axis direction from the orthogonal axis direction mechanical error and the set inclination of the mechanical axis.
