“…1 shows the field emission scanning electron microscope (FESEM) surface textures of Al-18%SiCp MMC after casting. The figure describes that at the time of fabrication of Al-SiCp MMC the Al-alloy is easily melt near about temperature 740 0 C but the SiC does not melt at that temperature because its melting point is near about 2730 0 C. But at that temperature SiC particles decomposing with the parent material which produces free carbon and that carbon deposition arises black colour on the Al-SiCp MMC surface (Hu et al, 2013;Srinivasa et al, 2014).

The objective of this paper is to optimize the process parameters by combined approach of VIKOR and Entropy weight measurement method during Electrical discharge machining (EDM) process of Al-18wt.%SiCp metal matrix composite (MMC). The central composite design (CCD) method is considered to evaluate the effect of three process parameters; namely pulse on time (Ton), peak current (Ip) and flushing pressure (Fp) on the responses like material removal rate (MRR), tool wear rate (TWR), Radial over cut (ROC) and surface roughness (Ra). The Entropy weight measurement method evaluates the individual weights of each response and, using VIKOR method, the multi-objective responses are optimized to get a single numerical index known as VIKOR Index. Then the Analysis of Variance (ANOVA) technique is used to determine the significance of the process parameters on the VIKOR Index. Finally, the result of the VIKOR Indexed is validated by conformation test using the liner mathematical model equation develop by responses surface methodology to identify the effectiveness of the proposed method.

“…SiC-particulates-reinforced Al matrix composites (SiC p /Al composites) possess many excellent physical and mechanical properties compared with conventional metal materials, such as high specific modulus, enhanced resistance to wear, low thermal expansion, and high thermal conductivity [1][2][3]. They have been widely used in aerospace structures, turbine engine blades, electronic packaging, satellite bearings, laser reflectors, and nuclear engineering [4,5]. However, due to the addition of the rigid ceramic particles, a material with low fracture toughness that is typically hard-brittle and difficult to cut, the machining of SiC p /Al composites is very difficult, and the main difficulties lie in low surface precision and poor edge quality.…”

In this work, a three-dimensional large-deformation thermo-elastic-plastic finite element model for oblique cutting was established to analyze edge defects during the machining of 17vol.% SiCp/2009Al composites. The formation process of edge defects at the workpiece exit during turning was investigated, and the influence of depth of cut, feed rate, and spindle speed on the edge defect sizes at the workpiece exit was explored. The results show that a negative deformation plane began to form as the cutting tool approached the exit end of cut, and the resultant cracks propagated towards the negative shear deformation plane, which led to workpiece edge defects. In addition, the size of edge defects increased with increasing depth of cut and feed rate, while the spindle speed had less influence on the size of edge defects. The numerical results of the effects of cutting parameters on edge defects were also compared to those of the turning experimental data, and were found to be in reasonable agreement.

Abstract. The goal of present research work is to investigate the Electrical discharge Machining process parameters namely current, pulse on time and combined equal weight percentage of silicon carbide and graphite on material removal rate, tool wear rate and surface roughness of hybrid metal matrix composites. Experimental trails are done by Taguchi's L27 orthogonal array. Signal to noise ratio is used to determine optimal setting of process parameters. Analysis of Variance is utilized to discover the most influential machining process parameters on output responses. This examination have shown results of ideal machining condition which can be utilized to boost material removal rate as well as to limit tool wear rate and surface roughness. Finally results are validated by confirmation Tests.
