Powder Mixed EDM (PMEDM) is a refined form of EDM in which finely ground powder that is conductive is added to the dielectric. Particles suspended in dielectric reduce the insulating properties of the material, increasing the inter-electrode gap, and thereby improving EDM performance and surface quality compared to conventional EDM. More recently, studies had been conducted on the use of mixed-powder dielectric to improve EDM's efficiency. Many scientists have become interested in PMEDM in recent decades. Including a metallic particle in the dielectric fluid not only makes it more conductive but also increases the gap between the workpiece and the tool that causes sparks. When powder is mixed into dielectric, material removal speeds up, surface quality improves, and tool wear is reduced. Particle attributes such as concentration, electrical conductivity, density, and size have an impact on processing variables and should be taken into account when choosing a powder for an operation. Researchers can use this review to better select powders for the PMEDM process by learning how different powders affect the process in question. [ABSTRACT FROM AUTHOR]
