Hardness Effects on Abrasive Flow Machining
Strojniški vestnik – Journal of Mechanical Engineering, 2013 Abrasive flow machining (AFM) is a manufacturing technique that uses the flow of a pressurized abrasive media to remove workpiece material. In comparison with other polishing technique, AFM is very efficient, suitable for the finishing of complex inner surfaces.

The application of polymers as abrasive media in abrasive flow machining
Mechanik, 2019 The characteristics of the products’ treatment by the abrasive flow machining (AFM) makes it an appropriate method of finishing the surface with complex geometry, e.g. holes or channels. Traditional methods of machining cause difficulties in obtaining a homogeneous roughness during finishing complicated shapes due to uneven distribution of abrasive ...
