Studying Surface Roughness in Abrasive Flow
Finishing of complex, miniaturized parts, especially of internal recesses is very difficult and time consuming process. Abrasive Flow Machining (AFM) is an appropriate finishing process for such finishing requirements. It uses abrasives laden polymeric putty with other ingredients to polish the surfaces. This medium is extruded backand-forth over the surface employing the hydraulic pressure sys...
متن کاملEffect of Process Variables in Abrasive Flow Machining
When an abrasive mixed with a polymer of special rheological properties and forced through a restricting medium, the abrasive and polymer will act as a self forming tool that precisely removes work piece material and improve the surface finish at those areas restricting to the medium flow. It is capable of machining areas which are difficult to reach by conventional machining and can be used to...
متن کاملAdvancement 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 ...
متن کاملNeural Network Modeling of Abrasive Flow Machining
This paper discusses the preliminary development of a neural network-based process monitor and off-line controller for abrasive flow machining of automotive engine intake manifolds. The process is only observable indirectly, yet the time at which machining achieves the specified air flow rate must be estimated accurately. A neural network model is used to estimate when the process has achieved ...
متن کاملMaterial Removal Mechanisms in Abrasive Flow Machining
Abrasive flow machining (AFM) is a process for the production of excellent surface qualities of inner profiles that are difficult to access and outside edges, as well as for deburring and edge rounding. The grinding medium used in AFM consists of a polymer fluid, the so-called base, in which the abrasive grains are bound. The grinding medium is pressed along the contours at a defined pressure a...
