Different methods of ELID grinding ELID is classified into four major groups based on the materials to be ground and the appli-cations of grinding, even though the principle of in-process dressing is similar for all the methods. The different methods are as follows.
A significant improvement in the strength of the Si 3 N 4 specimens was noted when finish ELID grinding was performed. This was the result of ductile regime grinding using the application of finish ELID grinding. Another method to improve the flexural strength of silicon nitride specimens will also be addressed in this paper.
