Abstract
The usage of composite materials has been increasing globally in all manufacturing industries. Nontraditional machining methods like electric discharge machining, ultrasonic machining, etc are used to accomplish better results in the machining of composite materials. In the present work, an attempt is made to study the study the effect of Wire Electric Discharge Machining (WEDM) parameters like pulse-on time, pulse-off time and peak current on Surface Roughness(Ra) and Material Removal Rate(MRR) in Aluminum Metal Matrix Composites(AMMCs). The composite material containing aluminum alloy as matrix, silicon carbide as reinforcement is produced by Stir casting technique. Experimentation was conducted in a series of tests called runs, in which changes are made in the input variables in order to identify the reasons for changes in the output response using Response Surface Methodology.
