Abstract

This paper is focused on novel electrode in-machine dressing strategy by means of EDM for seal slotted parts in aeronautical industry. The feasibility of in-machine electrode dressing applying a linear interpolation to the electrode to recover its frontal face has been analysed. The influence of different approaches in plate materials and parameters were studied. Dressing time, plate wear and geometrical accuracy for the different condition tested has been recorded. Ultrafine graphite as electrode material and mild steel and copper tungsteen as plate materials have been analysed in this work.
