Abstract

PURPOSE:To detect and distinguishably indicate the condition of discharge of normal electric discharge during spark machining, continuous arc discharge, short circuit, no discharge, thus easily adjusting each discharge machining condition to the best on the basis of the said indication. CONSTITUTION:Level gauges 6, 7, 8 are set with levels E1, E2, E3. The first level gauge 6 sets the level of E1 and applies the voltage of the level E1 and machining pulse power supply 1 onto a relative amplifier 9. In the same manner, relative amplifiers 10, 11 are applied with voltage of levels E2, E3 and machining pulse power supply 1. The output of relative amplifiers 9, 10, 11 is checked to detect and determine each discharge condition at timings T1, T2, T3 using AND gates 12, 13, 15-18, etc. Output terminals 22-25 give out judge signals of normal discharge, continuous arc discharge, short circuit, no discharge. The judge signals are indicated.
