“…Sliding at 0.5 m s −1 in an unreinforced Al7075 matrix and 2 m s −1 in an Al7075%-9% borosilicate glass powder (AG-9) composite resulted in significantly different wear rates. The wear resistance capability of filled composites was significantly increased [18][19][20] due to the hard and stiff borosilicate glass particles. Large amounts of heat are created between two surfaces, creating a self-lubricating tribo-layer that decreases the wear rate of composites [21][22][23].…”

“…In recent years, borosilicate reinforced aluminium composites have garnered significant attention for their lightweight nature, impressive strength-to-weight ratio, and improved mechanical properties. Achieving successful machining of these composites hinges on finely tuning machining parameters to ensure effective material removal, superior surface finish, and prolonged tool lifespan [18][19][20][21]. This review delves into existing research on optimizing machining parameters specifically for borosilicate-reinforced aluminium composites, aiming to offer a comprehensive snapshot of the current knowledge landscape in this domain.…”

Now-a-days, metal matrix composites based on pure aluminium are widely used as a replacement for a wide range of applications thanks to their high strength-to-weight ratio, ductility, and thermal conductivity. Micron-sized (10-3 mm) borosilicate (mixer of Silica (SiO2) and Boron Oxide (B2O3)) glass particles were used to create a dispersion in an aluminium matrix composite (Al7075- borosilicate glass MMC) utilizing a stir casting technique while in a liquid condition. The present study examines the effect of borosilicate glass particle content (0, 3, 6, and 9 wt. %) and changes in sliding velocity (0.5, 1, 1.5, and 2 m/s) on the wear behaviour of a composite rubbing against an EN31 steel disc at a constant load of 20N and a sliding distance of 1000 m. Analysis of wear showed that the presence of borosilicate glass increased the wear rate and countered the trend shown in the coefficient of friction. In a similar vein, the sliding velocity of the counter plate rotated faster resulted in a higher coefficient of friction and a higher wear rate. A reliable mathematical model is developed to find the best combination of machining parameters for Al7075-borosilicate glass metal matrix composite (MMC). This model will consider important performance measures like surface smoothness and material removal rate. The authors will also use a sophisticated statistical method called the Taguchi L9 orthogonal array design of experiments (DOE) to understand how different machining settings affect how easily the composite can be machined. By analyzing the results from the DOE, it can optimize the machining parameters for efficient and cost-effective processing. This work can lead to manufacturing innovation in the future.

“…For that advancement, EDM has been chosen for drilling on titanium material, and for a better surface fnish, abrasive fow fnishing process was added further. Te main purpose of Abrasive Flow Finishing (AFF) is to deburr, polish, and fnish hard-to-reach surfaces and edges by allowing an abrasive-flled polymer to fow from two vertically opposed cylinders [6][7][8][9]. Te medium (a mixture of viscoelastic material, say, polyborosiloxane, additives, and abrasive particles) enters the workpiece through the tooling [10,11].…”

It is quite evident that some of the experimental research works have been carried out by researchers in the area of spiral polishing using abrasive for surface finishing improvement but most of the experiment has been employed on Steel or Alloy Steel as a material. Very few number of research works have been performed by researchers across the globe on the Spiral Polishing Method of Titanium holes made by Electrical Discharge Machining (EDM). Therefore, experimental investigations were carried out in the area of Spiral Polishing and Finishing of EDM-drilled holes of various materials to meet the desired goal of demands on the surface quality. This experimentation aims to develop a novel method with spiral polishing using abrasive flow finishing. To explore the search investigation and find out the better surface finishing for through holes made on EDM, the process parameters have been designed using the Taguchi L16 orthogonal array with input parameters such as Current (I), Pulse on time (Ton), and Pulse off time (Toff). The addition of Boron Carbide Powder with Handwash, Glycerine, Shampoo, and Liquid Soap is used to decrease the Surface Roughness (Ra) with a ratio of 5 : 1. The Taguchi technique is used to assess the P/M process parameter setting for a given signal to noise (S/N) ratio.
