Experimental Investigation of the Pulse and Plasma Flushing Efficiency in Electrical Discharge Machining
نویسندگان
چکیده مقاله:
This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the pulse-on time, but plasma flushing efficiency decreases over 15(μs) pulse duration only under negative polarity of electrode. Based on the experimental results, the plasma flushing efficiency and pulse efficiency increases when the duty cycle increases in positive tool polarity.

Experimental Investigation of Wire Electrical Discharge Machining of NdFeB Permanent Magnets with an RC-Type Machine
This paper focuses on wire electrical discharge machining (WEDM) of devices made from commercially available sintered neodymium-iron-boron (NdFeB) rare-earth magnets that have been magnetized before machining. We conduct an experimental study to quantify the effects of the voltage and capacitance of an RC-type WEDM machine, as well as the magnet polarity, on slicing rate, mean kerf, and variati...
