Advanced engineering ceramics which are widely used as high strength refractory material for several industrial applications, always pose a challenging opportunity to machine them. Conventional methods of machining are difficult to shape them because of their high hardness and brittleness, while grinding is the only popular method to machine them, but shaping of ceramics in desired form is diff...

WEDM is a one of the non-conventional machining processes used for machining complex shape components and hard materials to produce intricate shapes on the wide variety of materials. With the increasing demands of high surface finish and high rate of MRR of complex shape geometries, WEDM machining process is now being replaced by non-traditional machining processes. According to this paper, opt...

The high-speed wire electrical discharge machining (WEDM-HS) machine has been more and more favoured by customers for the low manufacturing cost, the degree of automation and the advantages over the WEDM-LS in price performance ratio. However, the processing quality (the precision of form and position and the surface quality) of WEDM-HS is poorer than that of WEDM-LS, and the processing quality...

Electrical discharge machining process, is one of the most widely used methods for machining, the electrically conductive parts. In this way the tool is not in contact with the workpiece and the hardness of workpiece does not affect the machining speed. In Electrical Discharge Machining process, selection of the correct machining parameters are effective in final cost and the quality of the pro...

Micro-electric discharge machining (μ-EDM) is an important manufacturing process that is able to produce components and tools with micro-features. Improvement to this process has resulted in the use of powder mixed dielectric (PMD), which results in better surface quality and faster machining time. However, the presence of conductive powder in the dielectric fluid negatively affects the accurac...
