Photoelectrochemical three-dimensional processing method and device of laser bubble cavitation
InactiveCN101856753ALarge amount of erosionErosion is smallMachining electrodesElectrical-based machining electrodesElectrochemical responseManufacturing technology
The invention relates to a photoelectrochemical three-dimensional processing method and device of laser bubble cavitation, belonging to the non traditional combined machining field of the manufacturing technology. The method utilizes laser beam to irradiate the surface of workpieces in the solution and generate bubbles, as the bubble cavitation caused by bubble-collapsing combines with the electrochemical reaction so as to remove workpiece material under the action of photoelectrochemical reaction and realize etching and processing. In the device of the invention, a liquid crystal display of which the display of the grey level image is controlled by a computer is used as a mask plate, and when laser beam penetrates through the liquid crystal mask, an image with gray feature is generated to perform spatial modulation to the energy distribution in the laser spot. In the areas with higher laser radiation energy on the workpieces, the bubble cavitation is stronger, the speed of the photoelectrochemical reaction is higher and the etching removal rate is higher; in the areas with lower energy, the reverse happens, thus the processing of three-dimensional image can be realized. The device of the invention is applicable to the removal and processing of conductive metal material; and the display of the grey level image of the liquid crystal mask can be controlled by a computer, thus the processing efficiency of complex three-dimensional images can be increased greatly.
