PROBLEM TO BE SOLVED: To achieve a numerical control device which easily performs three-dimensional coordinate transformation and restoration by a working program. SOLUTION: The numerical control device is provided with a transformation matrix storage means 44 which stores a transformation matrix when an analysis means 40 decides that a command of the working program is a three-dimensional coordinate transformation command; a saved transformation matrix storage means 62 which stores a transformation matrix by reading it from the transformation matrix storage means 44; a clearing means 52 which reads a transformation matrix from the transformation matrix storage means 44 based on an analysis result by the analysis means, stores the transformation matrix in the saved transformation matrix storage means 62, and initializes the transformation matrix; and a transformation matrix restoration means 60 which stores the transformation matrix read from the saved transformation matrix storage means 62 in the transformation matrix storage means 44 based on a three-dimensional coordinate transformation and restoration command, and can issue a three-dimensional coordinate transformation command based on the transformation matrix read from the transformation matrix storage means 44.
