The method cuts a curved surface (SF) generated by interconnecting corresponding points(Mi, Ni; i=1,2...) on two curved lines (CV1, CV2) with a cutter (BT) of a milling machine having simultaneously controlled five axes or a wire electrode of a wire-cut electric discharge cutting machine. According to the numerically controlled cutting method, curve information specifying the two curved lines information on tool radius or wire radius, information on the direction of tool or wire compensation, and division information for dividing the curved lines are supplied as inputs. Using the above items of information an offset position at dividing points is determined. The cutter or the wire is then moved to the offset position to cut the curved surface. |
