Description

On the wire electrical discharge machining process of insulating ceramics, Si3N4 ceramics have the better machining properties than other material such as ZrO2, SiC. It was well known that mechanical and physical properties of ceramics material varied with the sintering conditions and additive. EDM properties are changed with variation of material characteristics. To clarify the effects of the physical properties on the WEDM process, several Si3N4 ceramics were WEDMed by the assisting electrode method. The relation of thermal conductivity and removal rate, surface roughness was evaluated. The differences of machining properties for each material are discussed with waveforms analysis and electrically conducive layer thickness.
