Abstract An experimental investigation was conducted to determine the effects of the recast layer, formed after the spark EDM, on the strength characteristics of the inconel 718 alloy. The parameters such as peak discharge current, current pulse duration, gap voltage and pulse off time were chosen to study the influence of machining characteristics ...

Experimental investigation of surface crack density and recast layer thickness of WEDMed Inconel 825
2020The present research attempts to analyze the surface topography of WEDMed Inconel 825 with respect to surface crack density (SCDi) and recast layer thickness (RCLt). Formation of cracks, recast layer and heat-affected zone are the major issues in determining the final performance of WEDM machined sample. In this study, WEDM characteristics viz.

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 ...

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.
