Analysis of discharge channel characteristics based on three-phase flow dielectric characteristics in USV-MF assisted WEDM-LS

In this paper, considering the effects of characteristics three-phase flow dielectric in discharge gap field on channels ultrasonic vibration and magnetic assisted low speed WEDM (USV-MF WEDM-LS), model channel including position size is established. Firstly, a mechanism bubble-particle bridging breakdown was proposed under working condition cutting workpieces with large thickness. Then prediction point USV-MF WEDM-LS based performed, FEM software COMSOL used to simulate analyze model. By comparing experimental results captured by high-speed camera, accuracy verified, it showed that can explain more accurately. Next, radius intensity, electric medium pressure, surface tension established, influence USV MF analyzed theoretically. The obtained solving partial differential equation MATLAB. According plasma channel, morphology workpiece simulated COMSOL. Finally, experiment photographing carried out verify above It trend same as results, error peak height value between within 6%.
