Wire-cut electrical discharge machining apparatus is provided with a wire-cut electrical discharge machining function and a laser machining function. The laser machining is used to effect coarse machining at high speeds. The finishing is effected by the wire-cut electrical discharge machining maintaining high precision. The wire-cut electrical discharge machining appts. is equipped with a laser oscillator (9) for laser machining, and a column (8) is equipped with laser beam irradiation means (10) which adjoins an upper wire electrode to a work (3) that is to be irradiated with a laser beam (12). The wire-cut electrical discharge machining appts. is also provided with a numerical controller which alternatingly switches the wire-cut discharge machining operation and the laser machining operation and moves relative positions of the wire electrode (6) and the work (3) as well as relative positions of the laser beam irradiation means (10) and the work (3) along predetermined loci.
