Abstract

Voltage pulse or current pulse can be used as the main monitoring parameter of the sparks that occur in micro electrical discharge machining (μEDM) process. The spark gap should be monitored for many purposes including study of material removal characteristics, which can be followed by tool wear monitoring and compensation. The system which fulfils the requirements of monitoring spark gap by using gap waveforms is called pulse discriminating (PD) system. The purpose of this research is to compare the capability of effective pulse discrimination using voltage and current pulses by online application of an algorithm written in LABVIEW separately. The comparison is based on the evaluation of the following responses - effective counting of total number of pulses and percentage of different kind of pulses that exist in μEDM.
