Abstract

The power spectral density (PSD) of the voltage and current waveforms acquired during micro-EDM millingexperiments are calculated and analyzed. The estimate of the PSD in the frequency domain allows to identify thepulse energy contribution in relation to the dynamics of the erosion process. The first results show that most of theenergy released by the micro-EDM generator in the sparking gap during the erosion process is concentrated at thefundamental frequency set by the end-user, which in turns means that the process is stable. However, thecontribution to the fundamental frequency is not provided by normal pulses only, but also by arcs. Nonetheless, arelevant number of unpredictable events (arcs and delayed occurrence) leads to several non-negligible subharmoniccontribution, which witnesses the presence of inductive currents generated during the erosion process.
