A key issue in ELID, according to Chen and Li is to balance the rate of removal of the metal bond by electrolysis and the rate of wear of the superabrasive particles .Although the superabrasive wear rate is directly related to grinding force, grinding conditions, and workpiece mechanical properties, the removal rate of the metal bond depends on ELID parameters such as voltage, current, and the ...

To successfully establish the ELID-grinding, it is important to properly select the electrolytic condition according to grinding conditions. Currently, the selection of electrolytic condition is mainly dependent on the operator's experience, which is one of difficulties preventing the successful application of ELID technique. In this study, an in-process measurement system of the insulating ...

(ELID) grinding is that the grinding wheel is continuously dressed even if the grains are very small (up to #3,000,000 mesh size) [9–11]. The first appearance of ELID grinding in the literature is probably in 1985, when Murata et al. [12] reported ELID grinding of ceramics using metal-bond diamond wheels with grain sizes smaller than #400.
