This study investigates the wear behavior of abrasive media used in Vibratory Mass Finishing Treatment (VMFT) and its impact on process performance. The primary objective is to establish the relationship between the evolving characteristics of Abrasive Media Mass Finishing (AMMF) and the efficiency of the finishing process. Particular attention is given to the mechanisms of media wear and their effect on cutting capacity and surface quality. Experimental analysis was conducted to evaluate how variations in AMMF properties, such as size, shape, and load volume, affect wear rates and finishing performance across different engineering materials. The results demonstrate that AMMF wear significantly influences process stability, material removal efficiency, and surface finish quality. Key wear mechanisms, including grain blunting, particle detachment, and self-sharpening effects, were identified as critical factors governing performance. The findings highlight that optimizing AMMF characteristics and monitoring their wear state are essential for maintaining consistent finishing quality. Furthermore, the study provides insights into selecting suitable media and operating conditions to improve process reliability and extend media life. This work contributes to a better understanding of wear evolution in VMFT and supports the development of more stable and efficient finishing operations.
