Abstract: This paper describes the influence of the EDM discharge pulse shape on the machining performances and material removal mechanisms of Si3N4-TiN. Dramatic differences of material removal, ranging from classical melting to chemical decomposition, are observed by applying different pulse shapes such as the iso-energetic or relaxation type discharge pulses. It not just leads to the change of surface texture and machining performances, but also has influences on the ceramic properties. An EDM strategy is developed for the production of ceramic components in Si3N4-TiN and validated through the fabrication of a high temperature mesoscopic gas turbine.
