PURPOSE:To simplify selection of tools, by selecting a hypothetical main cutter edge which inclines more in a cutting direction from the first and second main cutter edges of the tools for balance-cutting, and selecting a hypothetical subsidiary cutter edge which inclines move in the opposite side of the cutting direction from subsidiary cutter edges so as to carry out NC programming. CONSTITUTION:There is a case that the cutter tip configurations of tools on the first and second tool rests which are used in balance-cutting are different from each other. Then, a main cutter edge MB12 which inclines more in a cutting direction is selected for a hypothetical main cutter edge for balance- cutting from the main cutter edge MB11 of the first tool and the main cutter edge MB12 of the second tool. And, a subsidiary cutter edge SB11 which inclines more in the opposite side of the cutting direction is selected for a hypothetical subsidiary cutter edge for balance-cutting from the subsidiary cutter edge SB11 of the first tool and the subsidiary cutter edge SB12 of the second tool. And, even balance-cutting is carried out by these hypothetical balance-cutting tools, a cutter tip passage which is not to interfere a work is calculated, and NC programming is carried out. Therefore, the cutter tip configurations can be made freely.
