Abstract :Abrasive flow machining (AFM) is a non-traditional finishing method that is recently becoming popular. Increasing surface quality demands and developing manufacturing technologies need high costs and time. AFM process satisfies these demands in a short time period. In this study, the material removal model for a double-acting AFM and the experimental validation of the model was presented. The material removal model was based on the mathematical model suggested by Jain et.al [13] and the active grain numbers and the total material removal formulations were re-evaluated. A CFD analysis was carried out to determine the wall shear stress, velocity distribution, static and dynamic pressure values and used in the mathematical model. The experimental study is performed on the Ti-6Al-4V alloy using 400 mesh size SiC abrasive for 20%, 40%, and 60% abrasive concentrations by weight. The results of the experimental study were compared with the results of the mathematical model presented in the study. The differences between the results of the presented model and the experimental ones are very close to each other for all abrasive concentrations. By using the presented model, the AFM process parameters can be pre-determined according to the required final form.
