Abstract:

Wire-cut electrical discharge machining (WEDM) is one of the most emerging non-conventional manufacturing processes for machining hard to machine materials and intricate shapes which are not possible with conventional machining methods. This paper focuses on prediction and comparison of machining performance during Wire Electric Discharge Machining process of Aluminium- SiC in-situ composite to achieve minimum surface roughness. The control factors considered for this study are speed, wire feed, Pulse On-Time and Pulse Off-Time. The Universally known statistical software Minitab 16 is used for the research. The process parameters have been selected based on Taguchi’s L27 orthogonal array. The research reveals the better characteristics of Aluminium composite which a good scope in aerospace application. The predicted machining characteristics are in good agreement with the experimental values. Further the research can extend for different process parameters and various levels for the better optimal machining characteristics.
