Analysis of recast layer thickness and martensitic layer thickness in wire electrical discharge machining

Materials Today: Proceedings, 2021
Abstract Precision manufacturing is a challenging process in which high accuracy is required. Wire electrical discharge machining (WEDM) is one of the most vital machining processes in which precision manufacturing are possible. During wire electrical discharge machining (WEDM), machining surface needs to be more precise to maintain surface integrity,

Correlation of surface roughness and recast layer thickness in electrical discharge machining

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2015
Electrical discharge machining (EDM) is an extensively used method in the machining of electrically conductive materials. Recast or white layer formation is undesirable, but inevitable, result of EDM and needs to be understood and accurately determined to efficiently perform post-treatment processes for removing the recast layer caused by EDM process.

Experimental investigation of surface crack density and recast layer thickness of WEDMed Inconel 825

2020
The 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.

Study on recast layer thickness and residual stress during WEDM of SMAs

Emerging Materials Research, 2017
Shape memory alloys (SMAs) are difficult to machine by thermoelectric processes due to the affinity of titanium (Ti) for oxygen, and the specific properties of SMAs have been taken into account for the design of SMA actuators. In this investigation, wire electro-discharge machining of a specific SMA is investigated with specific reference to the ...

Recast Layer Thickness Characterization of Array of Micro Features Using X-Ray Micro Computed Tomography

SSRN Electronic Journal, 2017
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.

Effect of recast layer thickness on the mechanical characteristics of INCONEL 718 machined by spark EDM process

Materials Today: Proceedings, 2018
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 ...
