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.

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.

Estimation of Recast Layer Thickness in Rotary Tool EDM Process for Machining AISI D3 Tool Steel
Materials Today: Proceedings, 2017Abstract Out of the various non-traditional machining processes used these days, Electric Discharge Machining (EDM) has its own place for the machining of hard materials and creating intricate shapes in difficult-to-machine materials. The current research work focusses on the measurement of recast layer thickness of AISI-D3 tool steel using the ...

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.
