Research on Rotational Electrode and Inner Jetted Dielectric EDM Milling Flow Field Simulation and Experiment

Zhang Shukui,Wang Yanqing,Huang He,Bai Jicheng(Harbin Institute of Technology,Harbin 150001,China)  
The possibility of using water as dielectric has been demonstrated through theoretical analysis and flow field simulation.The reason for using positive polarity machining when using the water as dielectric in EDM Milling has been analyzed.Research on the pressure field,velocity field and removal in debris concentration distribution in the discharge gap of water with high velocity and pressure,and the impacts on micro procedure of electrical discharge and removal and thrown of material also have been researched,and validated by experiment.
