Spark erosion: electrode selection spark erosio

Electrodes electrode selection and machining are important factors in operating ram edm. with wire edm there is a constant supply of new wire, or electode material; with ram edm the electrodes wear. so knowing about electrodes is important in doing ram edm. see figure 11:1. a. function of the electrode.

Jun 01, 2003 an investigation was made into the combined technologies of electrical discharge machining and grinding edmg. a metal matrix cu/sic p electrode with a rotating device was made and employed to study the edmg technology.it was found that 3–7 times the normal electrical discharge machining edm material removal rate mrr could be achieved in edmg under suitable conditions of electrode grinding mill.Electrical discharge machining is one of the earliest nontraditional machining, extensively used in industry for processing of parts having unusual profiles with reasonable precision. in the present work, an attempt has been made to model material removal rate, electrode wear rate, and surface roughness through response surface methodology in a die sinking edm process.Jul 23, 2015 using copper tungsten in die sinker electrodes for edm dimensionally a far cry from tungsten wire with a diameter of 0.0010 0.025 mm is the use of tungsten for die sinker electrodes. taking the reverse shape, die sinker electrodes need to be dimensionally robust but also machinable with very fine features — sometimes as thin as fine wire grinding mill.The quality of spark eroded surface depends on many parameters. based on tests with copper electrodes the importance of the effect of surface roughness of the electrode is presented.

Sep 22, 2014 with spark erosion, edm spark temperatures many times higher than copper’s melting point, certain applications using copper electrodes suffer from unacceptable electrode wear. with the advent of graphite as an electrode material, superior metal removal rates have been attained with far less electrode wear.
