In the electrical discharge machining(EDM)ablation process,the oxygen take an important role in the process of oxidation heat,metal corrosion and cooling.Investigation on the effect of gas pressure on improving the gas flow rate,decreasing the molecular mean free path of gas,improving the oxidation diffusion velocity,accelerating the energy dissipation is carried out.Breakdown voltage,the breakdown delay and working voltage under different gas pressure is tested,results show that breakdown voltage and break...
