Electric Discharge Grinding (EDG) EDG is similar to EDM except that the electrode is a rotating wheel (usually graphite). Positively charged work pieces are immersed in or flooded by a dielectric fluid and fed past the negatively charged wheel by servo controlled machine table charged wheel by .
Electric discharge grinding of polycrystalline diamond materials . By S Ding, J Mo, M Brandt and R Webb. Abstract. ... This paper introduces a method to find optimal parameters in the Electrical Discharge Grinding (EDG) of PCD materials with Taguchi method. The theory and detailed procedures are presented, experimental results are analyzed.
Electrical discharge grinding (EDG) is becoming more prevalent in the manufacturing of polycrystalline diamond (PCD) tools. This paper concerns investigation of the effects of machining parameters, as well as finishing infeed, to the surface quality obtained when using EDG to erode PCD.
Also, after being eroded by 3step EDG process, there was an over 30% declination of residual stress compared with 2step machining. The results of the orthogonal cutting test showed that the wear amount and the thrust force of PCD inserts machined by 3step EDG .
Jan 06, 2015· Electrochemical discharge grinding Electrochemical discharge grinding (ECDG) is a hybrid process of electrochemical machining (ECM) and electrical discharge grinding (EDG). It is used for the machining of electrically conductive materials. This process uses nonabrasive graphite grinding wheel with no abrasive particles and an electrolyte.
