Performance Of EDM Die - Sinking Parameters On Material Characteristics Of LM6 Using Graphite Electrode

Nowadays, EDM die-sinking is one of the important processes to produce a product made from a hardness material with a close tolerance. EDM die-sinking process works effectively for machining deep holes and micro holes with high accuracy.In this study, graphite electrode used to machine aluminium all...
