【Abstract】 By using a counter and an operation microprocessor, this paper analyses the measuring method and designs an instrument of EDM sinking process in discharge state. This instrument takes samples of voltage,current signal and strong and weak of high frequency signals of detecting voltage amplitude, translates them into various time pulses in discharging state. And a counting unit turns these pulses into digital signals, then send them to a microprocessor. Finally various discharge time percentages are sent to the control tache.更多还原
