Design For Experimental Device For Polishing Hole By Abrasive Flow Machining

Abstract:Abrasive flow machining (AFM) is an effective way to the irregular surface and internal structure of parts polished, debarred, filleted finish machining and so on. Presently abrasive flow machining is primarily applied for aviation, aero-plane in China, but it hasn't been used widely. Because there are still many technical problems to be solved, such as:the studies on AFM equipment, preparation of abrasive and cutting mechanism. In order to further improvement of AFM technology, a lot of experimental research should be done. In this paper, one experimental device is designed specially for polishing the small holes whose diameters are 4mm and 0.3mm. The design of the experimental device contains the design of dynamic system, the design of the abrasive cylinder, the design of the fixture and the design of the bottom plate. By Pro/E design for the experimental device, and by ANSYS analysis of mechanical properties, and finally the test device can be verified to meet the test requirements, and achieve the test successfully. It is possible the design of the testing equipment will provide some useful information for the late experiments about the AFM, and offer some reference source for the design of AFM machine tools.
