“…For micro hardness testing Vickers hardness testing machine was used (Singh et al, 2005). In this test a square based pyramid type diamond indenter was used and the hardness variation on the weld interface as well as along the axis of shaft at the intervals of 1 mm on both the parent materials was obtained by applying a constant load of 500gf.…”

Abstract:The present study emphasizes on joints two industrially important materials AISI 304 with AISI 1021steels, produced by friction welding have been investigated. Samples were welded under different axial pressures ranging from 75MPa to 135MPa, at constant speed of 920rpm. The tensile strength, torsional strength, impact strength and micro hardness values of the weldments were determined and evaluated. Simultaneously the fractrography of the tensile tested specimens were carried out, so as to understand the failure analysis. It was observed that improved mechanical properties were noticed at higher axial pressures. Ductile failures of weldments were also observed at 120MPa and 135MPa axial pressures during fractography analysis.

“…They suggested that Graphite electrode is more suitable for rough machining while Copper electrode is a better option to achieve the better surface quality. The performance of Copper, Copper-Tungsten, Brass and Aluminium electrodes on the En-31 tool steel were tested by Singh et al [34]. They found Copper tool gives higher MRR, better surface finish, lower tool wear and overcut as compared to the other materials.…”

-Electrical Discharge Machining (EDM) is a thermo-electrical based non-contact material removal process for machining of the electrically conductive difficult-to-machine materials. The machinability of the EDM process is not affected by mechanical and physical properties of the workpiece materials. Even though, its performances are highly affected by the tool materials and their designs. Most of the research papers refer to enhance the productivity of the EDM process without considering the effect of the parameters related to the tool electrodes. Generally, the tool wear is the well known phenomenon of the EDM process that affects the plasma formation as well as surface quality and productivity. The aim of the present study is to summarize a report on the published works related to the tool electrodes materials, designs and their effect on the performances of the EDM process. Instead of this, the present paper also focuses to future research scope in the same field and discussed in the brief.

“…used in aerospace, aeronautics and nuclear industries. These materials also find applications in other industries because of their high strength to weight ratio, hardness and heat resisting qualities [1][2][3]. In EDM material is removed from the conductive material through the action of an electrical discharge of short duration and high current density between tool and workpiece.…”

“…The main disadvantages of electrical discharge machining are, it is time consuming and higher cost. So researchers focus their attention to reduce the cost [1]. Inconel 718 is a precipitation-hardened nickel-chromium alloy, so it is important to improve the process capabilities of EDM for machining of Inconel 718 and fix the appropriate range of selected variables for machining.…”

Electric discharge machining (EDM) is a non-traditional machining process; it is a well established machining option in many manufacturing industries throughout the world. There are no physical cutting forces between the tool and work piece while removing the material, it only uses thermal energy to machine electrically conductive parts regardless of hardness has been its distinctive advantage in the manufacturing industries. Inconel 718 is one of the alloy that have relatively poor machinability, due to its work hardening nature, retention of high strength at high temperature and low thermal conductivity. This paper presents the results of experimental work carried out in electrical discharge machining of Inconel 718 using two different tool materials namely copper and brass. The outline of this work is to optimize the process parameters like current, voltage and pulse on time for maximum material removal rate and minimum tool wear rate. The response surface analysis is used for the data analysis while RSM's D-optimal method is used to solve the multi response optimization. It is observed that copper electrode perform better than brass for the tested work material.
