PROBLEM TO BE SOLVED: To solve a problem that it is not easy to set an approaching route, difficult to form a data of an NC program locus and necessary to take working time. SOLUTION: A worker adds a data of a three-dimensional model of a metal mold prepared by a computer supported designing system to a numerical control device (S1). The numerical control device finds a data of a machining shape locus from the data of the three-dimensional model of the metal mold, finds a data of a position of a center of gravity of a core by computing a data of a three-dimensional shape of the core and finds a data of the approaching route from these data (S2 to S6). Thereafter, a favorable data of the NC program locus is provided from the machining shape locus, the position of the center of gravity of the core and the data of the approaching route (S9).
