Electrolytic in-process dressing (ELID) is a grinding technique used to generate high-quality surfaces on hard and brittle material. Oxide layer formed on grinding wheel during ELID grinding heavily influences the surface roughness of the workpiece. To study the microscopic structure of the oxide layer and model the thickness of it, we …
