AFM may be performed once, as a one-way flow process, or repeatedly as a two-way flow process. Magnetic Abrasive Finishing Week 7: Faculty who teaches manufacturing. Abrasive flow machining AFMalso known as abrasive flow deburring [1] or extrude honing[2] is an interior surface finishing process characterized by flowing an abrasive -laden fluid through a workpiece.

Conventional abrasive finishing processes CAFP: In abrasive flow nptle, the abrasive fluid flows through the workpiece, effectively performing erosion.

Abrasive flow machining

The fluid is forced through the workpiece by a hydraulic ram[3] where it acts as a flexible file, or slugmolding itself precisely to the shape of the workpiece. Abrasive Flow Finishing Week 6: Deburring and Edge Handbook Illustrated ed. The effects of various input parameters on the outputs as well as the use of cutting fluids in various finishing process will be discuss.

This page was last edited on 25 Juneat The lectures will introduce the basic principles of material removal by use of abrasives particles and material removal mechanism of different abrasive process.

Introduction to Abrasive Machining and Finishing Processes

flpw 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. 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.

Retrieved from ” https: Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them. They may be manually operated, or automated using CNC. A variety of numerical problems and MCQs, discussions will also be included. He has published over 30 research articles in internationally reputed journals, 2 Patents, 2 Edited Books and 6 Book chapters.
