An investigation on machined performance and recast layer properties of AISI H13 steel by Powder Mixed-EDM in fine-finishing process

Powder-mixed electric discharge machining (PMEDM) has been studied with many different powders. However, limited works have used the tungsten carbide powder in the PMEDM process and investigated its effects on machined performance (MP) and recast layer properties (RLP) of samples. Thus, to fill the missing gaps on the PMEDM. In this paper, an investigation of the effect of main process parameters, including peak current (Ip) and pulse on time...
