An estimating the effect of control process variables on kerf width in wire EDM of AZ91 magnesium alloy by Taguchi method

Abstract

The target of the current research study is to contemplate the impacts of diversecontrol parameters in WEDM, for example, wire tension, wire speed, discharge duration on and Pulse off time over kerf width (KW) and to get the ideal arrangements of process parameters. The trial work comprises of machining of Magnesium AZ91 alloy material utilizing Wire EDM (WEDM).The wire (tool) material was brass wire by means of zinc coated. The observations of the cutting process are based on L27 Taguchi's array for optimizing the control variables for these composite. The criticalness of each cutting parameters are associated to the most impacting factors which influences the procedure reactions. The ideal cutting variables are selected from the outcomes. Minitab V.18 software are developed for establishing good relationship between machining variables, such as wire feed, pulse duration time, wire tension & pulse off duration with the cutting control process criteria kerf width.
