The nature of AFM makes it ideal for interior surfaces, slots, holes, cavities, and other areas that may be difficult to reach with other polishing or grinding processes.〔 Due to its low material removal rate, AFM is not typically used for large stock-removal operations,〔 although it can be.〔 Abrasive flow machining was first patented by the Extrude Hone Corporation in 1970. ==Process== In abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them. The fluid is forced through the workpiece by a hydraulic ram,〔 where it acts as a flexible file, or slug, molding itself precisely to the shape of the workpiece.〔 The highest amount of material removal occurs in areas where the flow of the fluid is restricted; according to Bernoulli's Principle, the flow speed and pressure of the fluid increase in these areas, facilitating a higher material removal rate.〔〔 The pressure exerted by the fluid on all contacting surfaces also results in a very uniform finish.〔 AFM may be performed once, as a one-way flow process, or repeatedly as a two-way flow process. In the two-way flow process, a reservoir of medium exists at either end of the workpiece, and the medium flows back and forth through the workpiece from reservoir to reservoir.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Abrasive flow machining」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
