| Abstract: | The problem and reason of the existence for EDM electrode wear was analyzed. The waveform control method of low electrode for the energy-saving pulse generator was proposed ,and the control circuit was designed. The process for copper and steel object research and experiment was introduced,and the initial value of the trapezoidal wave current was determined. Through the research, this paper have under the condition of two kinds of waveform ,the influence of different electrical parameters on the key technology,and obtained the rule. Energy-saving power supply related research results so as to realize the low electrode wear in roughing laid a foundation. |
