Electric Discharge Machining Method for various Metal Matrix Composite Materials

Abstract

Among all the advanced Metal matrix composite (MMC) materials is among the important and beneficial materials for industry because of their characteristics such as high specific strength, high corrosive resistance, good wear resistance, light weight, and high thermal coefficient. It is very critical to do operation due to high hardness and reinforcement of the MMC by using conventional machining which is responsible for retard the development of MMC. Machining of MMC by using conventional machining process is a serious cause of higher Tool Wear Rate (TWR) because of abrasive properties of reinforcement particles. Machining of such materials can be done by using different type of non-convectional machining processes like that Laser beam machining (LBM) and water jet machining (WJM). But both processes are limited to linear machining only. This Articles represent a literature survey on Electric discharge machining (EDM) of reinforced MMC and different methodology used such as Analysis of variance (ANOVA), Response Surface Methodology (RSM), Taguchi methodology etc. which helps in optimizing the results. This review is analyzing the suitable process parameters and machining performance for machining of MMC and also reveals the research work area in which maximum research work can be done in future.

Systematic review of optimization techniques for laser beam machining

“…The process of optimisation acts as a directing compass, making it possible for manufacturers and researchers to traverse this complex process with accuracy. Also, the process of optimisation aims to achieve a delicate equilibrium between competing goals such as the rate of material removal, the quality of the surface, and the amount of thermal damage caused by the process [34][35][36][37]. Further, several response characteristics like surface roughness, dross height, kerf width, kerf taper angle, and striation can be optimized.…”

Investigation of Hardness and Microanalysis of Sintered Aluminum-Based Supplemented Metal Matrix Machined Composites

“…Despite other non-traditional machining methods, the electrical discharge machining (EDM) process was found to be the most promising one for the removal of material from AMMCs. EDM removes the material by erosion through melting and vaporizing in the presence of dielectric fluid [12][13][14]. Spark erosion occurs between the tool and the workpiece gap [15].…”
