ABSTRACT:
A numerical control method for moving a tool along a commanded curve on a curved surface, which includes entering the curved surface defined by data representing a mathematical expression or by a group of numerical data, entering numerical control data specifying a projected curve obtained by projecting the commanded curve onto a predetermined plane, successively finding positional coordinates on the commanded curve through use of the curved surface data and numerical control data specifying the projected curve, and controlling the position of the tool on the basis of the positional coordinates.
