Abstract
There is prepared V-CAD data obtained by dividing external dataconsisting of boundary data of an object into rectangular parallelepiped cellshaving boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cellspositioned on the inner side of the object and boundary cellsincluding a boundary face, and mold data and mold processing data used to manufacture the object are generated from data of a reference plane which at least partially comes into contact with the objectand the V-CAD data. Further, in the mold processing data, a plurality of the processing toolsare selected in descending order of a size in accordance with sizes of the internal cellsof a processing portion, and the processing toolis moved in a plane of the mold and in the thickness direction, thereby processing the mold. As a result, by using the V-CAD data, the NC processing program for mold processing can be simplified, and the mold processing time can be greatly reduced.
