Abstract: The functions of the passivating film, the factors influencing the thickness and compactness of the film and the control strategies of the film state in Electrolytic In-process Dressing (ELID) precision grinding were analysed. The loop current, which can characterise the film state was monitored and the experiments of the ELID grinding were conducted in the active controlling of the film state.

Keywords: electrolytic in-process dressing; ELID grinding; precision grinding; state control; passivating films; silicon nitride.
