Plasma electrochemical jet flow combined machining method and device

The invention relates to the technical field of combined machining, and discloses a plasma electrochemical jet flow combined machining method and device. Electrolyte forms jet flow through a jetting device to be jetted on a workpiece, and plasmas are generated on the surface of the workpiece by applying proper voltage, so that an oxidation film generated by electrochemical jet flow on the surface of the workpiece is broken through, electrolytic plasma machining and electrochemical jet machining are combined, and machining of chemical inert materials is achieved. A workbench is arranged on a rack of the plasma electrochemical jet flow combined machining device, a clamp is arranged on the workbench, and the jetting device comprises a nozzle which faces the clamp and is used for spraying electrolyte to the workpiece. The combined machining mode of electrolytic plasma machining and electrochemical jet machining can be achieved only by clamping a to-be-machined workpiece on the clamp, connecting the nozzle to the
