Abstract:This study explores the enhancement of surface roughness in various types of dies—stepped, flat, and chamfered—used in fastener production through Abrasive Fluid Machining (AFM) technology. Unlike traditional hand polishing methods, AFM provides a faster and less skill-dependent alternative. Surface roughness values (Ra and Rz) for each die type were measured before and after the AFM process, and the impact of AFM on surface quality was assessed. The results demonstrated a significant reduction in surface roughness across all three die types. Notably, the stepped die exhibited reductions of up to 85.82% in Ra and 80.13% in Rz. The flat die showed a decrease in Ra and Rz values by 84.43% and 79.65%, respectively. Similarly, the chamfered die experienced reductions of 74.46% in Ra and 77.58% in Rz following the AFM process. These findings indicate that AFM is a highly effective method for improving the surface quality of fastener dies, thereby potentially extending their operational lifespan.
