The effect of various process parameters on machining performance was investigated. The input parameters considered are current, pulse on time, pulse off time and tool lift and their effect on Material Removal Rate, Tool Wear Rate and Surface Roughness had been analysed. The Taguchi method and traditional desirability function analysis was used to formulate the multi response experimental layout, Optimal machining conditions were identified for the given tool & work piece combination and also it was found that the results were in line with the literature data.

In the present work Al-SiC-B 4 C metal matrix composite is prepared from sintering of mechanically alloyed powder (ball milling) in powder metallurgy processes. Three different combinations of compositions in volume fraction were chosen namely 90%Al 8%SiC 2%B 4 C, 90%Al 5%SiC 5%B 4 C and 90%Al 3%SiC 7%B 4 C. An attempt has been made to study the characteristics of developed metal matrix composite. As increase in percentage of B 4 C the micro hardness of the metal matrix composite has increased significantly. The microstructure of the prepared metal matrix composite reveals the uniform distribution of particles in metal matrix.

Through powder metallurgy technique Al Composites are prepared. The pressure required for compaction was optimized and pressure density relation was established. Optimum compaction pressure has been identified as 170 MPa and also compaction pressure density relationship was established based on the Heckel's expression. Various compacting stages were identified. Optical microscopic studies reveal the proper distribution of reinforcements in metal matrix. Hardness and microstructure studies have been performed on prepared metal matrix composite

Ceramic reinforced aluminum composites are difficult to machine by conventional machining processes. In this work, ceramic reinforced aluminum composites are machined by Electric Discharge Machine (EDM). The goal of this study is to focus on the influence of EDM settings on Al6061 Metal Matrix Composite (MMC) reinforced with Silicon Carbide (SiC) and Boron Carbide (B4C) particles. The MMC is prepared by stirring casting route, then the workpiece is mounted on the electric discharge machine to perform the machining. Because MMC contains high abrasive ceramic (SiC and B4C) particles that are difficult to machine using traditional machining methods, an electrical discharge machine is used for machining. The experiments were conducted with four process parameters like Pulse current (I), Pulse off Time (P-Off), Pulse on Time (P-On), and Tool Lift (TL) with three levels in each parameter to examine the response measures such as Material Removal Rate (MRR), Surface Roughness (SR), Tool Wear Rate (TWR) and Surface Crack Density (SCD). The experimental results reveal that the surface crack density, MRR, SR, and TWR increases with an increase in current and pulse in time. The optimal combinations of process parameters were identified. Obtained optimal machining conditions are I input level at 9 Amps, P-On input level at 20 µs, P-Off input level at 50 µs, and Tool Lift input level at 4.5 µs with results of 0.103g/min MRR, 0.022 g/min TWR, 4.108µm SR and 0.0048 µm SCD.

Electric discharge machining (EDM) shows a potential technique for machining hybrid metal matrix composites. An investigation is done on hybrid metal matrix composite for response parameters like MRR, TWR by conducting a range of experiments with choosing typical process parameters such as peak current, tool lift, pulse-on time and pulse-off time.
