| Abstract: | The temperature fields during ultrasonic vibration aided electrical discharge machining in gas are simulated with ANSYS method and FEM software. The distribution of temperature fields during the discharging machining using single pulse with different power density are analyzed. The influence rules of different pulse width and power density to the shapes of the dents and the roughness of the finished surface are obtained. The data gained from the simulations is proved to be accordant with the data gained from experimentation. |
