ABSTRACT:
There is prepared V-CAD data obtained by dividing external data12consisting of boundary data of an object into rectangular parallelepiped cells13having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells13apositioned on the inner side of the object and boundary cells13bincluding 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 object1and the V-CAD data. Further, in the mold processing data, a plurality of the processing tools2are selected in descending order of a size in accordance with sizes of the internal cells13aof a processing portion, and the processing tool2is 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.
