Advancement in surface finishing by abrasive flow machining : Review

Abrasive flow machining (AFM) is a manufacturing technique that uses the flow of a pressurized abrasive media to remove work piece material. In comparison with other polishing technique, AFM is very efficient, suitable for the finishing of complex inner surfaces. In recent years, hybrid-machining processes have been developed to improve the efficiency of a process by clubbing the advantages of different machining processes and avoiding limitations. It is experimentally confirmed that abrasive flow machining can significantly improve surface quality of nonlinear runner, and experimental results can provide technical reference to optimizing study of abrasive flow machining theory. This project is a genuine effort to optimize all the available modifications and permutation of abrasive flow machining in order to get the best available surface finish with minimum changes in the pre existing setups at no or very little cost.
