In this study, MIE values measured with two different explosion tubes, HARTMANN and MIKE 3, are compared. Generally, MIKE 3 apparatus provides MIE results, which are equal or lower to those measured with the HARTMANN apparatus; this is particularly true for the energy ranges between 1 and 10mJ and higher than 100mJ. Differences observed can modify samples classification according to their sensi...

To grasp the characteristics of air discharges of electrostatic discharge (ESD) guns, time-variant spark gap voltage waveforms at low charge voltages are discussed. Through the application of our proposed circuit approach using measured discharge current waveforms and frequency characteristics of an ESD–gun, the time-variant spark gap voltage waveforms for air discharges of an ESD–gun can be es...

In this paper, fuzzy logic integrated with the Taguchi method is used to optimize Wire Electro Discharge Machining (WEDM) process with multiple quality characteristics. Rough machining with EDM gives poor surface finish and has micro cracks and pores. Finish machining gives better surface finish but with very poor machining speed (MRR). Spark gap width is one of the important performance measur...
