The current research deals with Taguchi-coupled grey relational analysis (GRA) multiobjective optimization of wire electric discharge machining (WEDM) for better surface roughness (Ra) and the material removal rate (MRR) over magnesium/halloysite nano tube/zirconium (Mg/HNT/Zr) metal matrix composite (MMC). Hybrid composites are created through powder metallurgy route by varying weight percenta...

Unconventional machining process finds lot of application in aerospace and precision industries. It is preferred over other conventional methods because of the advent of composite and high strength to weight ratio materials, complex parts and also because of its high accuracy and precision. Usually in unconventional machine tools, trial and error method is used to fix the values of process para...

In this study, the eff ects of cutting parameters on kerf and surface roughness were experimentally investigated in WEDM. Al 7 475-T7 351 alloy was selected as the work material to conduct experiments. The factors selected for the optimization are the pulse on time, table feed rate and the wire speed, each of the factors in three diff erent levels. An optimal parameter combination of the WEDM p...

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf wi...
