Influence of different tool electrode materials on EDMed surface integrity of AISI P20 tool steel
Surface integrity in electro-discharge machining (EDM) has been proven to be one of the major challenges in recent years. The current study focused on investigating the influence of different tool electrode materials such as copper, brass, and graphite and various process parameters like discharge c...
