Tool electrode wear in electrical discharge of small diameter holes

Tool electrode wear in electrical discharge of small diameter holes

In the paper, the problem of obtaining small diameter holes in workpieces made of high speed steel by electrical discharge machining was formulated. A fulfil factorial experiment was designed and materialized, taking into consideration the tool electrode diameter, pulse on time and pulse off time as...
