ALUMINUM METAL MATRIX INVESTIGATION OF PROCESS PARAMETERS IN DRILLING COMPOSITE REINFORCED BY USING ELECTRICAL DISCHARGE MACHINING.
Abstract
This paper presents an investigation on the effect and optimization of machining parameters and material removal rate (MRR) in wire electrical discharge machining operations. The experimental studies were conducted under unreliable pulse duration, open circuit voltage, wire speed and dielectric flushing pressure. The settings of
machining parameters were determined by using Taguchi experimental design method. A single large part made of composites can replace many metal parts. Composite materials can be embedded with sensors, which can monitor fatigue and performance. They have high stiffness to density ratio thereby providing greater strength at lighter
weights. The use of light-weight materials means an increase in the fuel efficiency of automobiles and airplanes. Drilling is one of the most frequently used machining processes in industries owing to the need for component assembly in mechanical structures. In this project, a Polyester Resin specimen alone, treated and untreated specimen of Kevlar composites are considered and Polyester Resin is used as the matrix material. Alumina particle reinforced aluminum matrix composites (Al/C/Fe3O4) have dazzling physical and chemical properties than those of a conventional metal; however, their deprived mach incapacity lead to worse surface superiority and serious cutting tool wear. In this study, wire electrical discharge machining is adopted in machining (Al/C/Fe3O4) composite. In the experiments, machining parameters of pulse-on time were changed to discover their effects on machining performance, and surface roughness.
