【Abstract】 The detection principle of WEDM discharge position of shunt current method was analyzed with theory. According to this principle,the hardware system of WEDM discharge position detection was built. And the software was programed based on LabVIEW. The acquisition of the current signal,conversion of analog electrical signal,real-time observation of the discharge position and data storage has been realized. The variable section cutting experiment showed that the detection error is less than 3.3 mm and the detection accuracy is high.更多还原
