| Summary: | Electro discharge machining (EDM) as a die sinking process has taken off in 1943. Since
then it was known as a non-conventional machining process and its application was limited for
processing only electrically conductive materials. Later on, due to the widespread applications, this
EDM process is considered conventional as usual. However, in the recent years EDM has gone
through considerable changes especially with dielectric fluids, simple to complex geometry, meso to
micro sized structures, nanometric surface finish, and so on. In addition, the application of EDM has
also been extended for processing electrically semi-conductive and non-conductive materials like
ceramics and composites. This paper discussed micro electro discharge machining of non-conductive
ceramic materials. It includes detail process development, modelling of material removal rate and
surface finish which include the effect of multi spark and random spalling conditions. |
