1. A machining path creating device for wire electric discharge machines, which creates a machining path for machining a keyway in a side surface of a round hole, the machining path creating device comprising:
a keyway shape input unit that inputs a shape of a keyway to be machined; a hole shape input unit that inputs a diameter and a center position of the round hole; and a machining path creating unit that creates a machining path, wherein the machining path creating unit compares a keyway depth input by the keyway shape input unit with the diameter of the round hole input by the hole shape input unit, when the input keyway depth is smaller than the diameter of the round hole, the machining path creating unit determines the input keyway depth as a cut depth of the keyway which is a distance from the hole side surface to a keyway bottom, and when the input keyway depth is larger than the diameter of the round hole, the machining path creating unit determines a difference between the input keyway depth and the diameter of the round hole as the cut depth of the keyway. |
