| Abstract: | In this paper the problem of accurate gap state recognition in micro-EDM is discussed.Firstly the voltage waveforms in the electrode anti-copy experiment are analyzed,which indicates these voltage waveforms are of different spectral characteristics.Then the idea of spectrum feature recognition for gap state is stimulated by the analysis results and the spectral analysis method of gap state is proposed.To realize the idea by programming,the FFT algorithm is used.Through MATLAB simulations and debug on-line,a... |
