PURPOSE:To eliminate the need for an analysis of graphic data by a person's help by deciding the direction of a linkage order of coordinate data from a large/small relation of the coordinate of a graphic element of a closed graph. CONSTITUTION:From a graphic information input device 2, coordinate data of a graphic element of a closed graphic is inputted, and set to a closed graphic data setting part of an NC data generating device 3 in order of linkage. Subsequently, a controller 1 decides whether a linkage of the coordinate data is clockwise or counterclockwise by a large/small relation of an X component and a Y component of the coordinate data, based on this coordinate data of the graphic element which has been set, and generates NC data. Accordingly, NC data is generated without analyzing the graphic data by a person's help and working by NC can be executed. |
