Introduction to Abrasive Machining and Finishing Processes

Manufacturing Engineering and Materials Processing. D Mechanical Engineering, Production Engineering.

An abrasive flow machine normally includes two medium chambers equipped with hydraulic rams, a fixture for holding nptwl workpiece, and a clamping system that holds all the components tightly together. Retrieved from ” https: 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. Magnetic Rheological Finishing Week 8: It will be e-verifiable at nptel.

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


Faculty who teaches manufacturing. Deburring and Edge Handbook Illustrated ed. Abrasive flow machining AFMalso known as abrasive flow deburring [1] or extrude honing[2] is mptel interior surface finishing process characterized by flowing an abrasive -laden fluid through a workpiece.

Abrasive flow machining

Abrasive Flow Finishing Week 6: This course will define the areas of application of traditional as well as non-traditional abrasive finishing processes in the manufacturing industry. They may be manually operated, or automated using CNC. Final score will be calculated as: From Wikipedia, the free encyclopedia. Magnetic Abrasive Finishing Week 7: Views Read Edit View history.

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 abdasive grinding processes.

NPTEL :: Mechanical Engineering – Advanced Manufacturing Processes

This page was last edited on 25 Juneat Abrasive flow machining was first patented by the Extrude Hone Corporation in Fliw using this site, you agree to the Terms of Use and Privacy Policy. He did his B. Introduction conventional abrasive processes,Introduction to abrasive processes,Grinding Process Week 2: 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 effects of various input parameters on the outputs as npyel as the use of cutting fluids in various finishing process will be discuss. 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.

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

Certificate will have your name, photograph and the score in the final exam with the breakup.
