Title

Electro Discharge Drilling (EDD) of Rice Husk Ash Reinforced Aluminium Matrix Composite Using Different Electrode Shapes

Abstract

Electro discharge drilling (EDD) is a non-contact machining process which capable of producing holes of high aspect ratio, thus improving overall productivity and reducing the cycle time. It is a hybrid machining process which combines electric discharge machining (EDM) and drilling of electrically conducting hard materials..In the present study rice husk ash (RHA) particles have been incarnated in aluminium metal matrix by stir casting process. The RHA reinforced in aluminium matrix increases the mechanical properties and decrease the density of the composite material. This study investigates machinability of AA6063/ 5% RHA metal matrix composite using modified EDD set up with the help of Taguchi’s Design of Experiments (DoE) methodology. L18 orthogonal array is used in Taguchi optimization technique. The process parameters that have been considered as control factors are peak current, pulse ON time, gap voltage and electrode rotation. Electrode tool geometry with conical and circular shape has been considered as noise factor. The performance measures that have been selected are material removal rate (MRR), tool wear rate (TWR) and diametric overcut (DOC). The main aim of the present study is to investigate the effect of the tool electrode geometry and rotation of tool electrode on the performance measures. It has been analyzed that electrode tool geometry plays major role in the increase of material removal rate (MRR) followed by electrode tool rotation, peak current, pulse on time and gap voltage High improvement in material removal rate has been observed due to effective flushing capability due to rotary effect of electrode. TWR decreases in an inverse relation with pulse on time. Peak current has high significant role on DOC because with increase in peak current DOC also get increases. Furthermore, conical shape tool electrode most prominently affects the MRR and TWR amongst all of the parameters.
