Abstract

The invention discloses a laser-jet flow electrolysis combined machining double-pipe tool electrode and a milling machining method, and belongs to the field of laser-electrolysis combined machining. The double-tube tool electrode comprises an optical lens, an outer cathode tube, an inner inclined convex ring, an array outer inclined hole, a mesh, an inner cathode tube and an annular laser beam. The outer cathode tube is coaxially sleeved outside the inner cathode tube, an annular laser beam is adopted, an inner inclined convex ring is arranged at the lower end of the outer cathode tube, and a mesh is arranged at the lower end of the inner cathode tube. In the milling process, the annular band laser is started, and a power supply is switched on. A workpiece to be machined is corroded to form a groove under the synergistic effect of a laser irradiation thermal field, an electric field, an electrochemical field, a flow field and the like, and electrolyte is supplied in a spraying and sucking mode, so that the annular cavity is filled with the electrolyte, and machined products and bubbles are taken away in time. The outer diameter of the double-tube tool electrode reaches the centimeter level, large-area milling of a metal component can be achieved, the machining process is stable, and efficient and high-precision machining can be achieved.

Description

technical field [0001] The invention relates to a laser-jet electrolytic composite processing double-tube tool electrode and a milling processing method, and belongs to the field of laser-electrolytic composite processing. Background technique [0002] Thin-walled and weakly rigid metal components are often processed by mechanical milling, electrical discharge machining, laser machining, and electrolytic machining. They each have advantages, but also limitations. Mechanical milling is the mainstream method for processing thin-walled and weakly rigid metal components, but the tool wear is serious and the workpiece is easily deformed. The efficiency of EDM and laser processing is low, the thermal stress generated is large, and defects such as micro-cracks and recast layers appear on the surface of the workpiece. Electrolytic machining has high efficiency, good surface quality, no tool electrode wear, no machining stress, and no defects such as recast layers. It is one of the...

Problems solved by technology

[0007] In summary, the existing laser-electrolysis composite processing technology can basically only realize the processing of simple shape features such as holes and grooves with a feature size of millimeters or less, and it is difficult to perform high-efficiency and high-precision processing of large areas and high material removal rates.
