“…Images obtained clearly illustrate the debris buildup, fibre breaking, spalling, and peripheral surface degradation. [12]. Abdallah R et al investigated the related impact of cut directions on the rate of metal removal of CFRPs by WEDM and found that there is 16% increase in the maximum MRR during cutting in similar direction to fibre direction as compared to cutting in lateral direction [13].…”

Composites are being used since decades and imparting excellent properties comparatively. It may be used in numerous industries because of its light weight and specific strength. Machinability of these materials is a concerned aspect. Conventional and The composites have been machined using unconventional machining techniques. Conventional methods are less suitable than non-conventional quoting the best surface finish and ability to machine complex parts. This article investigates the suitability of thermo-electric process for the machining of composites for higher surface quality and material removal. It includes the study of machining by die sinking, wire cut, powder mixed electric discharge machine in different matrix based composites along with the variation of reinforcement. Electric Discharge Machining (EDM) finds its suitability in machining of different metal matrix composites (MMC) more than the Polymer Matrix Composite (PMC) and Ceramic Matrix Composites (CMC). Variation in input parameters listed as Pulse duration, Voltage, Peak Current and Polarity is studied to obtain the optimum resulting parameters as Material Removal Rate (MRR), Surface Roughness (SR), Electrode Wear Rate (EWR) and Kerf Width. Material removal in PMC is 16% more in parallel fibre direction than with perpendicular. Low electrical conductance and high hardness of CMCs limits the use of EDM while natural ceramics are found more suitable for machining. Gap voltage, pulse on time and current are found most crucial in machining MMCs while quantifying material removal and surface roughness.

The machining of aluminium metal matrix composites (aluminium MMCs) presents a dynamic landscape of opportunities and challenges, with electrical discharge machining (EDM) emerging as a promising technique. This review article systematically navigates the intricate interplay between AMMCs’ unique characteristics and the EDM process. Through a comprehensive analysis of existing literature, we uncover the underlying mechanisms that govern the machining dynamics of AMMCs, exploring their compositional variations, reinforcement distribution and thermal properties. The article delves into the opportunities offered by EDM, such as precision machining of intricate geometries, inherent thermal control and the ability to navigate the varying hardness levels in AMMCs. Furthermore, the review addresses the challenges that arise, including electrode wear, surface integrity preservation and the influence of reinforcement particles on material removal rates. The authors highlight the role of parameter optimisation in achieving desirable machining outcomes, underlining the need to strike a balance between material removal efficiency and surface finish quality. Additionally, environmental considerations in EDM of AMMCs are discussed, emphasising sustainable machining strategies in line with contemporary ecological concerns. As the field of advanced materials and manufacturing continues to evolve, this review article provides valuable insights for researchers, engineers and industries seeking to harness the potential of EDM in machining AMMCs. By navigating the intricate landscape of opportunities and challenges, this article contributes to a holistic understanding of the nuanced relationship between EDM and AMMCs, laying the foundation for future advancements in precision machining of these composite materials.
