Abstract : Abrasive flow finishing (AFF) is a novel non-traditional finish-machining process developed as a method to debur, polish, and radius surfaces and edges by flowing an abrasive laden media over otherwise difficult to machine areas and surfaces. The technique is particularly useful on internal surfaces because abrasion action occurs where ever the media flow is restricted, appropriate tooling is employed to direct the media to the target areas to be finished. The article identifies the parameters of abrasive flow finishing (AFF) that significantly affect the quality characteristics, material removal (MR) and change in surface roughness (ΔRa), on brass components bearing multiple holes. Taguchi’s parameter design approach has been applied to investigate the effect of process parameters and for optimization of the process parameters for enhanced quality characteristics. The beauty of the Taguchi technique lies in its ability to directly indicate an optimal setting of process parameters for any particular quality characteristic, although this particular optimal parameter setting may not produce the desired results for all the quality characteristics, which represent the overall/total quality of the product. This calls for a need for multi-characteristic optimization of the complete process for improving the overall quality of the products. This objective is achieved by the application of Utility concept to identify the optimal setting of process parameters which yields enhanced overall quality characteristics in finish-machining of multiple holes in brass components.
