Optimization of operating parameters is an important step in machining, particularly for operating unconventional machining procedure like Wirecut Electro Discharge Machining. Since wire-cut EDM has experienced explosive growth in application users demand and need maximum productivity and through-put, increased accuracy, and predictable performance. Also machines and job requirements vary great...

Metal matrix composites, in particular, Aluminium Matrix Composites are gaining increasing attention for applications in aerospace, defence and automobile industries. The use of nonconventional machining techniques in shaping aluminum metal matrix composites has generated considerable interest as the manufacturing of complicated contours such as dies. Electrical discharge machining (EDM) appear...

Due to the high mechanical strength of metals used in implant manufacture, which makes them difficult work with using other machining techniques, electrical discharge (EDM) is frequently employed production implants. In this study, effect powder ratio and EDM parameters CoCrMo alloy, widely, powder-mixed on surface roughness machined part was investigated through response methodology. AISI 316L...

Purpose: In this paper, the effects of various process parameters of WEDM like pulse on time (TON), pulse off time (TOFF), gap voltage (SV), peak current (IP), wire feed (WF) and wire tension (WT) have been investigated to reveal their impact on material removal rate of hot die steel (H-11) using one variable at a time approach. The optimal set of process parameters has also been predicted to m...

The objective of this paper is to determine the optimal setting of the process parameters on the electro-discharge machining (EDM) machine while machining AISI H13 tool steel. The parameters considered are pulse current, pulse-on-time, pulse-off-time and gap voltage ; whereas the responses are Tool wear ratio (TWR) and material removal rate (MRR). The optimal setting of the parameters are deter...

Wire electrical discharge machining (WEDM) is a special form of traditional electrical discharge machining in which the electrode is a continuously moving conducting wire. The mechanism of metal removal in wire electrical discharge machining involves the complex erosion effect from electric sparks generated by a pulsating direct current power supply. The sparks generated between two closely spa...

Electrical discharge machining (EDM) is one of the important processes to produce mold components. When using EDM process, surface quality, processing time, accuracy, and electrode cost must be considered. The wear main factor that causes error on geometric especially workpiece corner. Therefore, this study proposes a novel design improve accuracy for process. Firstly, effect current, diameter,...
