Non-traditional finishing procedures have become increasingly important in recent years, and it is critical that these techniques can benefit from composite materials. One of the most recent methods of surface preparation is called as Abrasive Flow Machining (AFM). As a result of its advantages including light weight, good strength, and low cost, composite materials have displaced traditional materials. It is used to mill composite materials that have a high proportion of Tungsten Carbide (WC) content (Al 6082/WC composites with 30 to 70 % Tungsten Carbide content). Taguchi's philosophy can be employed to study the MRR, Surface roughness (Ra) and surface topography. Extrusion pressure is found to be the most important element in determining MRR and ΔRa. It is done using the Taguchi approach to improve the response parameters (MRR and ΔRa).
