In-Process Truing/Dressing of Grinding Wheels by WEDG and ELID

Abstract

This paper proposes a novel in-process truing method by employing Wire Electrodischarge Grinding (WEDG) and describes its experimental results. This method is incorporated with electrolytic in-process dressing (ELID) and is implemented on a precision grinding machine. As a result, surface roughness could be maintained at less than 0.51lm ·Ry, and form accuracy could be maintained at approximately 0.7Ilm.
