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.

Grinding and lapping Metalworking. Magnetic Abrasive Finishing Machininy 7: Abrasive flow machining was first patented by the Extrude Hone Corporation in By using this site, you agree to the Terms of Use and Privacy Policy.

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. They may be manually operated, or automated using CNC. D Mechanical Engineering, Production Engineering. He has published over 30 research articles in internationally reputed journals, 2 Patents, 2 Edited Books and 6 Book chapters. Abrasive flow machining AFMmachinkng known as abrasive flow deburring [1] or extrude honing[2] is an interior surface finishing process characterized by flowing abraskve abrasive -laden fluid through a workpiece.

Abrasive flow machining

The lectures will introduce the basic principles of material removal by use of abrasives particles and material removal mechanism of different abrasive process.

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.

In abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. It will be e-verifiable at nptel.

Abrasive flow machining – Wikipedia

AFM may be performed once, as a one-way flow process, or abrasvie as a two-way flow process. Abrasive Flow Finishing Week 6: This page was last edited on 25 Juneat Magnetic Rheological Finishing Week 8: Conventional abrasive finishing processes CAFP: Introduction conventional abrasive processes,Introduction to abrasive processes,Grinding Process Week 2: Certificate will have flo name, photograph and the score in the final exam with the breakup.

Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them.

Retrieved from ” https: This course will define maachining areas of application of traditional as well as non-traditional abrasive finishing processes in the manufacturing industry. Deburring and Edge Handbook Illustrated ed. Views Read Edit View history.

He did his B. The effects of various input parameters on the outputs as well as the use of cutting fluids in various finishing process will be discuss. In the two-way flow process, a npteel of medium exists at either end of the workpiece, and the machiningg flows back and forth through the workpiece from reservoir to reservoir. From Wikipedia, the free encyclopedia. A variety of numerical problems and MCQs, discussions will also be included. Final score will be calculated as: Faculty who teaches manufacturing.
