Investigating the Effect of Brass Electrode on Inconel 718 on Electrical Discharge Machine

Electrical Discharge Machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). Inconel 718, which is widely used in the Medical, Marine, Architectural and food processing industries, is used as a work material. The tool electrode materials used are brass. Experiments are conducted using face centered central comp...

Investigation of Electric Discharge Machining of Inconel 718 Using Special Graphite Electrode

Electric Discharge Machining is a non-conventional machining process, used to machining difficult to machine materials. The major problem faced while doing EDM is high tool wear rate, end wear, corner wear , surface roughness and low material removal rate,. In this research work experimental investigations have been made to find the machining characteristics of high density ultra fine graphite ...

Optimization of machining parameters and wire vibration in wire electrical discharge machining process

Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. During the WEDM process, the wire behaves like a metal string, straightened by two axial pulling forces and deformed laterally by a sum of forces from the discharge process. Major forces acting on the wire c...

Temperature Measurement and Numerical Prediction in Machining Inconel 718

Thermal issues are critical when machining Ni-based superalloy components designed for high temperature applications. The low thermal conductivity and extreme strain hardening of this family of materials results in elevated temperatures around the cutting area. This elevated temperature could lead to machining-induced damage such as phase changes and residual stresses, resulting in reduced serv...
