Experimental Investigation of White Layer Formation on Machining Silicon Steel in PMEDM Process

Silicon, 2020
The silicon steel can be easily machined using electrical discharge machining process due to its higher strength. Since the white layer thickness and propoerties can affect the surface performance measures in the process, it is important to investigate the effects of process parameters on white layer. In the present study, an experimental investigation

How Suspended Particles Affect Surface Morphology in Powder Mixed Electrical Discharge Machining (PMEDM)

Metallurgical and Materials Transactions B, 2012
The effect of SiC powder mixing into the dielectric liquid on surface topology and structure of interstitial free (IF) steel has been studied. Four process parameters, namely pulse duration, pulse current, concentration of powder, and type of dielectric liquid material, have been selected as varying parameters.

Influence of the Agglomeration Phenomenon on the Recast Surface in PMEDM Environment

2020
The agglomeration phenomenon that occurs in PMEDM environment is one of the significant obstacles in enhancing the removal operation in this environment. This phenomenon has been investigated by the prior studies to improve the microhardness (MH) and recast layer thickness (RLT). However, these studies have not focused on the type of agglomeration that
