Abstract
A method of wire electric discharge machining by which an electric discharge is generated in a gap between a wire electrode (1a) and a workpiece (2) so that the workpiece (2) is machined, includes the steps of: a first step in which electric discharge machining is conducted in a dielectric liquid (4a); a second step in which electric discharge machining is conducted in mist (7); and a third step in which electric discharge machining is conducted in gas (8), such that the machining process is changed over when straightness of the workpiece (2) becomes a predetermined value. It is possible to provide a method of wire electric discharge machining, the productivity of which is high, suitable for highly accurate machining.
Claims3
