Modeling of Recast Layer in Micro-Electrical Discharge Machining
Journal of Manufacturing Science and Engineering, 2010 The thickness of recast layers produced during electrical discharge machining (EDM) is an important process performance measure as it may indicate an extent of crack propagation in a machined surface or thickness of a functional layer alloyed onto a machined surface.

Parametric analysis of recast layer formation in wire-cut EDM of HSLA steel
International Journal of Advanced Manufacturing Technology, 2016This paper presents an experimental investigation to determine the main wire electrical discharge machining (WEDM) process parameters which contribute to recast layer formation in high-strength low-alloy (HSLA) steel. Influence of process parameters, namely, pulse-on time, pulse ratio, power (discharge current), pulse (spark gap), and wire speed, has ...

Using WECM to remove the recast layer and reduce the surface roughness of WEDM surface
Journal of Materials Processing Technology, 2019Abstract When the workpiece is sliced by using wire electrical discharge machining (WEDM), owing to the material removal mechanism of melting and evaporation, numerous overlapping discharge craters and recast layer can be generated on the workpiece surface, leading to the high surface roughness.

Electrolytic removal of recast layers on micro-EDM microstructure surfaces
The International Journal of Advanced Manufacturing Technology, 2020Micro-EDM technology is widely used in the field of micro-fabrication due to its low cost, non-contact, and other processing characteristics. The EDM method involves molding parts by implementing the principle of melting metal at a high temperature, which results in a thin recast layer on the surface of the workpiece.
