Study on the Positive EDM Based on the Field Emission Theory

Article Preview

Abstract:

With different processing parameters, both the machining efficiency and the wear rate of electrode materials are enhanced along with the increase of real discharging power and the valid discharging time. However, the increasing degree of wear rate is far lower than that of machining efficiency.
