Natural fibers are dominating many composite industries due to their unique properties such as reusability, biodegradability, and environmental safety. Tamarind fruit fiber (TFF) stands out among the various fruit fibers and has been discovered in large quantities being discarded from the food processing industries. However, many natural fibers are extracted from their sources, which results in deforestation and environmental degradation. As a result, in today's world, recycling waste into new useful products is the primary concern in any field of engineering. In light of this, the current study used TFF obtained from agro industries and processed into fibers, which were then mixed with an unsaturated polyester matrix to create a natural composite material. Furthermore, by considering process parameters and their levels for conducting experiments, an orthogonal array has been achieved using Taguchi's design approach.

The advanced lifestyle demands materials that are light and robust, and aluminum and its alloys are commonly used in various engineering components due to their exceptional properties such as light weight, enhanced strength, and being economically affordable. Due to their superior mechanical properties, such as strength and flexibility, are commonly used in various industrial applications. Metal Matrix Composites (MMCs) are very essential materials used in several applications as they are more robust and harder than any conventional material.

Stainless Steel 304 (SS304) is a nickel–chromium–based alloy that is regularly used in valves, refrigeration components, evaporators, and cryogenic containers due to its greater corrosion resistance, high ductility, and non-magnetic properties, as well as good weldability and formability. Multiple regression analysis was used to establish empirical relationships between process variables. Additionally, the established regression equations are employed to predict and compare experimental data. Due to the increasing demands for high-quality surface finishes and complex geometries, traditional methods are being replaced by non-conventional techniques such as wire EDM. This process, which emerged from the electrical discharge machining concept, mainly involves creating intricate components. WEDM results in a high degree of precision and excellent surface quality. Due to the complexity of WEDM, the processing parameters cannot be selected by using the trial-and-error method.
