Abstract
There is a heat-affected zone in laser processing that affects the quality of the process. However, laser and tube electrode electrolytic composite processing has no heat-affected zone and no microcracking processing method. This method is subject to plasma breakdown during the machining process, which affects the quality of the machining. A real-time observation platform has been set up for the study of laser transport stability mechanisms in electrolytes. Focusing lens electrolyte breakdown, laser power density, breakdown frequency threshold, etc. were studied for 25mm, 50mm, and 77mm focal lengths, and it was found that breakdown was not easy to occur under the 77mm focusing lens. On the basis of this research on the tube electrode length, laser incidence angle, and other factors affecting the stability of processing, it was found that the laser incidence angle has an impact on the laser energy density distribution, but does not affect the laser focusing center of gravity position, and the increase in the length of the tube electrode helps to improve the laser energy density distribution. Using this processing method, a large depth grating-type workpiece was successfully processed on stainless steel, verifying the stability of the method of laser and tube electrode electrolytic composite processing.
