In this study, the eff ects of cutting parameters on kerf and surface roughness were experimentally investigated in WEDM. Al 7 475-T7 351 alloy was selected as the work material to conduct experiments. The factors selected for the optimization are the pulse on time, table feed rate and the wire speed, each of the factors in three diff erent levels. An optimal parameter combination of the WEDM p...

A wire electrical discharge machined (WEDM) surface is characterized by its roughness and metallographic properties. Surface roughness and white layer thickness (WLT) are the main indicators of quality of a componen...

Due to the widespread use of titanium alloy in various applications, such as maritime transportation and aviation, process mass production this material has become more challenging. Traditional methods removing materials have high wear rates slow processing speeds. This prompted development new techniques that can handle complexity material. Wire Electrical Discharge Machining (WEDM) is a metho...

In this paper, wire electrical discharge machining of D3 tool steel is studied. Influence of pulse-on time, pulse-off time, peak current and wire speed are investigated for MRR, dimensional deviation, gap current and machining time, during intricate machining of D3 tool steel. Taguchi method is used for single characteristics optimization and to optimize all four process parameters simultaneous...

In Wire Electrical Discharge Machining (WEDM) the breakage of the cutting tool (the wire) reduces the process performance and the required accuracy. Previous works of authors showed that the behavior of the basic signals of the process (current and voltage) can be employed to detect degraded situations that can lead to wire breakage. In particular, different types of degraded behaviors in two c...

Modernization of mechanical industry has lead to the increase in demand for hard and tough materials and thus various non traditional methods have been developed in order to machine such hard and tough materials. Wire Electric discharge machine is one of the most commonly used machine which is employed in machining of conductive metals of any hardness or that are difficult or impossible to cut ...
