He has published over 30 research articles in internationally reputed journals, 2 Patents, 2 Edited Books and 6 Book chapters.

Abrasive Flow Finishing Week 6: He did his B. Deburring and Edge Handbook Illustrated ed. In the two-way flow process, a reservoir of medium exists abrasivf either end of the workpiece, and the medium flows back and forth through the workpiece from reservoir to reservoir.

AFM may be performed once, as a one-way flow process, or repeatedly as a two-way flow process.

Manufacturing Engineering and Materials Processing. Abrasive flow machining was first patented by the Extrude Hone Corporation in 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 abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. From Wikipedia, the free encyclopedia. Magnetic Abrasive Finishing Week 7: They may be manually operated, or automated using CNC.

This page was last edited on 25 Juneat The effects of various input parameters on the outputs as well as the use of cutting fluids in various finishing process will be discuss. 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. Introduction conventional abrasive processes,Introduction to abrasive processes,Grinding Process Week 2: It will be e-verifiable at nptel.

Certificate will have your name, photograph and the score in the final exam with the breakup. An abrasive flow machine normally includes two medium chambers equipped with hydraulic rams, a fixture for holding the workpiece, and a clamping system that holds all the components tightly together. Conventional abrasive finishing processes CAFP: Retrieved from ” https: Magnetic Rheological Finishing Week 8: Grinding and lapping Metalworking. A variety of numerical problems and MCQs, discussions will also be included.

Abrasive flow machining

Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them. D Mechanical Engineering, Production Engineering. Final score will be calculated as: 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.
