Optimization of Process Parameter of Wire Electrical Discharge Machine by Response Surface Methodology on Inconel-600

in the present paper, the study has been made to optimize the process parameters during machining of Inconnel-600 by wire electrical discharge machining (WEDM) using response surface methodology (RSM). Four input process parameters of WEDM (namely Peak Current (IP), Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Feed rate (WF)) were chosen as variables to study the process performance in t...

Optimization of Process Parameters in Wire Electrical Discharge Machining of Inconel X-750 for Dimensional Deviation Using Taguchi Technique

Dynamic Strain Aging of Ni-base Alloys Inconel 600 and 690

Dynamic strain aging (DSA) and jerky flow phenomena in the commercial Ni-base alloys Inconel 600 and 690 have been investigated. Tensile tests were performed in the strain rate range of 10 to 10 s at temperatures of 100 – 600 C. No remarkable difference in the DSA behaviour of Inconel 600 and 690 alloys was observed. Tensile properties of the studied alloys in the DSA temperature range, and typ...

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...

Machinability Investigation of Inconel 657 in High-speed Turning

A high strength nickel chromium alloy (50Cr-50Ni-Nb alloy), commonly referred to as IN-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. The purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of Inconel 657. The considered parameters...
