OPTIMIZATION OF TRIBOLOGICAL PROPERTIES OF WIRE ARC ADDITIVE MANUFACTURED SPECIMENS USING GREY BASED TAGUCHI METHOD

Abstract

The present paper describes the streamlining of tribological properties of Wire Arc Additive Manufacturing (WAAM) specimens utilizing a grey-based Taguchi Method. Aluminium 4043 MIG wire withdiameter of 12mm is used to fabricate the samples with the assistance of the Cold Metal Transfer (CMT) machine. By following L9 Taguchi method, nine specimens are preparedapplying CMT machine. These specimens are formed by selected process parameters such as gas pressure, current, and nozzle to tip distance. Corrosion, Friction, and Wear tests were predictedby the tests on the specimens. The significant factors the minimization of corrosion, minimization offriction wear rate etc, are identified by applying the grey-based Taguchi Method. Grey based ANOVA is additionally performed using MINITAB.
