"The phenomena occurring between the electrodes in electrical discharge machining (EDM) are still not fully understood. Poor quantitative knowledge of the Sources of variability affecting this process hinders the identification of its natural tolerance limits," researchers in Wales report.
"This paper presents a systematic methodology for developing statistical models to show the relationship between important machining performance data (material removal rate (MRR), tool wear ratio (TWR), and surface roughness R-a) and the input machining parameters (pulse current and pulse-on time) in the EDM and ultrasonic-assisted EDM (US/EDM) of tungsten carbide. The models ...
