A machining path creating device for wire electric discharge machines creates a machining path for machining a keyway in a side surface of a round hole. The machining path creating unit compares a "keyway depth" and a diameter of the round hole input by an operator. The machining path creating device determines that the input "keyway depth" is a cut depth when the input "keyway depth" is smaller than the diameter of the round hole and that a value obtained by subtracting the diameter of the round hole from the input "keyway depth" is the cut depth when the input "keyway depth" is larger than the diameter of the round hole.
