Numerical Simulation of Cathode Erosion in EDM Process

摘要：

A numerical model of cathode erosion in EDM process using finite element method is presented. Using this model, numerical simulation of the single spark of EDM process has been carried out with parameters such as conduction, convection, the latent heat of phase change, thermal properties of material with temperature and gauss distribution of heat flux to predict the temperature distribution in the discharge point of cathode as a result of single discharges in EDM process. The simulation result shows the trend of dynamic temperature distribution of heat -affected zone and well explains mechanism of material removal in EDM process.
