Comparative Experimental Investigation with Different Wire Electrodes on SS440C Component Using Wire Cut EDM

EasyChair Preprint 3353

Abstract

Today Competition among the manufacturing industries at global scale is looking for creating faster production with precision and tight tolerances. Wire cut Electric Discharge Machining (W-EDM) is one of the latest non traditional machining processes used in industrial applications. It is suitable for machining works on a variety of materials like aluminium, titanium and alloys, super alloys, maraging steel. Among these materials very few studies are performed on SS440C which has high hardness, superior corrosion resistance and strength These materials are widely used in aerospace, defence industries for making complex parts. In this paper our target is to select the best possible outcomes in terms of Material Removal Rate and surface Roughness. Wire electrodes of Brass wire and zinc coated brass wire with 0.25 mm diameter are used .Experiment is based on Taguchi L₉ orthogonal array. Signal to Noise Ratio (S/N) and ANOVA is performed using MINITAB statistical software.

Keyphrases: ANOVA, Material removal rate, S/N ratio, SS440C, Surface roughness, WEDM
