2. Description of the Related Art A wire electric discharge machine is one of machine tools that automatically control a machining speed according to a machining load condition.
In a wire electric discharge machining apparatus, electric discharge is performed while maintaining a gap amount between a wire electrode to which a voltage is applied in a machining fluid and a workpiece at an optimal value for maintaining an optimal electric discharge state. Actually, the average machining voltage is kept at a constant value because a substantially linear relationship is established between the gap amount between the wire electrode and the workpiece and the average machining voltage obtained by smoothing the machining voltage. The processing speed is controlled as follows.

In the wire electric discharge machining described above,
Since a close relationship is established between the gap amount between the wire electrode and the workpiece, the processing speed and the processing voltage,
