Modeling of Recast Layer in Micro-Electrical Discharge Machining
Journal of Manufacturing Science and Engineering, Transactions of the ASME, 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 ...

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, 2015Electrical 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 ...

Study on recast layer thickness and residual stress during WEDM of SMAs
Emerging Materials Research, 2017Shape 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 ...

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.

Journal of Laser Applications, 2020
With the rapid development of high-power lasers, efficiency of laser cutting and thickness of cutting material have been greatly increased. In this study, a 10 kW fiber laser was used to cut 18 mm thick 316L stainless steel sheets. The surfaces and cross sections of samples were observed by an optical microscope and a scanning electron microscope.
