Examination of Oxidation Sites for Electrolytic In-Process Dressing (ELID) Grinding using SEM

Abstract Details

, Doctor of Philosophy, University of Toledo, Mechanical Engineering.
Electrolytic in-process dressing (ELID) is a grinding technique used to generate high quality surfaces on hard and brittle material such as ceramics and sapphires. Compared to the use of conventional wheel sharpening techniques (dressing), ELID greatly reduces grinding wheel wear and grinding forces, while improving surface quality and dimensional accuracy. 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 conducted a previously reported study on metallic bonded prism samples with major adjustments and implementations. The parameter studied are voltage, electrode-grinding wheel gap, and coolant flow rate. Scanning Electron Microscopy (SEM) images of cross-section of the oxidation sites were captured and compared and oxide layer thickness was accurately measured. The voltage, gap, and coolant flow pattern were found to significantly affect the forming of the oxide layer. SEM images provide evidence that ELID grinding can achieve high levels of surface finish.
