Comparison of Experimental and Theoretical Results of Tool Wear Rate in Electrical Discharge Machining
Abstract: Though electrical discharge machining (EDM) process is capable for complex and precise machining of materials irrespective of their hardness, it has certain limitations like low material removal rate (MRR), high tool wear rate (TWR), etc. which restrict its application areas. In EDM, material removal from workpiece and tool takes place by means of sparking between them which is a quite complex process. So, it is difficult to predict material removal …
