Finite Element Analysis of Tool Wear Rate in Electrical Discharge Machining and Comparison with Experimental Results
Abstract: Electrical discharge machining (EDM) is one of the precise non-traditional machining processes in which desired shape is obtained in workpiece using electrical sparks. In EDM, material removal from workpiece and tool takes place by means of successive sparks occurring between them. The tool wear is a critical problem in EDM as the change in tool shape directly affects the final shape of the workpiece. In this paper, finite element analysis …

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 …

Experimental Validation with CFD Analysis of Radiation Shield Plate for Cryopump Application
Abstract: Cryopump is used in fusion reactor to evacuate the plasma exhaust from the torus vessel and to achieve the ultra high vacuum. The radiation shield is an important part of cryopump as it prevents direct radiation heat load on cryopanels from outer shell. A sample of radiation shield plate was tested for pressure drop and heat transfer. It consists of polished stainless steel sheets which are spot welded in diamond …
