Destructive characterization of recast layer on reverse micro EDM-ed (RMEDM) surface renders the component unusable for its intended application. X-ray micro computed tomography (µCT) is a non-destructive technique widely used for characterization of internal structures of different materials.

In this study, the optimization of recast layer thickness and surface roughness (SR) simultaneously in a Wire-EDM process by using Taguchi method with fuzzy logic has been applied. The Wire-EDM process parameters (arc on time, on time, open voltage, off time and servo voltage) were optimized with considerations of multiple performance characteristics ...

Journal of Laser Applications, 1999
The machining of ceramic components using conventional techniques is slow and expensive due to low yields. High power lasers are capable of machining these materials at far greater speeds. However, the performance of ceramic substrates is dependent on the quality of the processed region, with specific reference to the level of microcracking.

Previous studies have shown that using hydrogel as the electrolyte in electrochemical machining (ECM) to remove the recast layer produced by electrical discharge machining (EDM), employing a hydrogel with higher ion concentration or a narrower gap between the electrode and the workpiece can significantly improve machining performance.

Surface Review and Letters
Monel K 400 is a potential superalloy that is used in heat exchanger piping, process vessels, gasoline, and portable water owing to superior mechanical properties at zero temperature. Square holes are needed in the high-temperature application components and are difficult to machine using conventional methods.
