Abstract
Disclosed is a numerical control method for positionally controlling a movable element of a machine tool in such a manner that numerically controlled machining is performed along a projected path obtained by projecting a programmed path, lying on a predetermined plane, onto a plane of projection inclined at a predetermined angle with respect to the first-mentioned plane. The method includes the steps of entering data specifying a programmed path on the predetermined plane, subjecting the entered data to a projective transformation in accordance with entered projection angle data to generate projective transformation data specifying the projected path, and performing an interpolation on the basis of the projective transformation data to produce an output signal indicative of the results of the interpolation, and positionally controlling the movable element on the basis of the projective transformation output signal.
