Wire electric grateful dead silicone mold discharge machining (WEDM) promise to be effective and economical techniques for the production of tools and parts from conducting ceramic blanks.However, the manufacturing of nanocomposite ceramics blanks with these processes is a long and costly process.This paper presents a new process of machining nanocomposite ceramics using WEDM.
WEDM uses water based emulsion, polyvinyl alcohol and distilled water as the machining fluid.Machining fluid is a primary factor that affects the material removal rate and surface quality of WEDM.The effects of emulsion concentration, polyvinyl alcohol concentration and distilled water of the challenge gravel grinder machining fluid on the process performance have been investigated.
