Device and method for machining materials by combining electrochemical discharging and laser

摘要

A device and method for machining materials by combining electrochemical discharging and laser belong to the field of special combined machining. Combined machining through electrochemical discharging and laser is carried out on transparent crisp and hard materials; an electrochemical discharging circuit is formed in an electrolyte solution by means of an auxiliary electrode and a tool electrode; a laser beam generates a focus on a surface of a sample, when energy reaches a certain value, an impact stress and a cavitation stress are produced; and laser energy and spark discharging cooperatively act on a workpiece from an upper direction and a lower direction, so that effective combination of two kinds of energy is guaranteed, the energy density of a machining area is improved, and the corrosion removing speed of a machined sample is increased.
