摘要
The invention discloses a method for classifying electro-discharge machining wave patterns by using a delay circuit, and a method for preventing arcs by classifying the electro-discharge machining waves. The voltage or current waves which are generated during an electro-discharge machining operation are classified by using high and low reference levels. Then the signals are delayed, inverted and AND-logic-combined to obtain a monitoring signal. The voltage or current waves are sampled immediately before the off-state of the delayed and inverted pulse, thereby classifying the electro-discharge machining waves. Thus the voltage or current waves which are generated during an electro-discharge machining operation are classified. Then, by utilizing the result of the classification, the occurrence of arcs is prevented.
