An experimental approach to Abrasive Flow Machining (AFM) process

A non-conventional finishing method known as abrasive flow machining (AFM) is used to deburr, radius, polish and remove layer of components in a wide range of applications. The process is relatively new. A semisolid viscoelastic/ visco-plastic abrasive-laden mixture was used to remove material. The process embraces a wide range of feasible applications including automotive parts, aerospace, oil industry, medical components, etc. After design and built of a the apparatus, the effects of different parameters such as number of cycles, abrasive media flow speed, abrasive mesh size, and concentration of abrasive on material removal and surface finishes were studied. The experiments showed that AFM process results in high quality surface finishes
