In wire electric discharge machining in which electric discharge energy is supplied between a wire electrode (1a) and a workpiece (2) by a machining electric power supply means (16) so as to machine the workpiece (2) when the wire electrode (1a) and the workpiece (2) are relatively traveled with each other by a positioning means, there are provided a first process in which rough machining is conducted in a working solution (4a) and a second process in which finish-machining is conducted in gas (7) such as air, oxygen, nitrogen or inert gas, and the positioning means is controlled by a control means (17) so that a relative traveling speed of the wire electrode (1a) with the workpiece (2) in the second process can be set at a constant rate not lower than a predetermined rate at which a short circuit can not continue between the electrodes for a predetermined period of time and more which has been previously set according to a required specification. It is possible to realize a high accuracy and quality of wire electric discharge machining and also it is possible to realize an enhancement of productivity.
