Introduction to Abrasive Machining and Finishing Processes – Course

A variety of numerical problems and MCQs, discussions will also be included. This page was last edited on 25 Juneat Tlow 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.

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


This course will define the areas of application of traditional as well as non-traditional abrasive finishing processes in the manufacturing industry.

It will be e-verifiable at nptel. Abrasive particles in the fluid contact raised features on the surface of the workpiece and remove them.

The lectures will introduce the basic principles of material removal by use of abrasives particles and material removal mechanism of different abrasive process. Retrieved from ” https: Abrasive flow machining was nnptel 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.

Introduction to Abrasive Machining and Finishing Processes

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 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.

Magnetic Rheological Finishing Week 8: Grinding and lapping Metalworking. They may be manually operated, or automated using CNC. The effects of various input parameters on the outputs as well as the use of cutting fluids in various finishing process will be discuss.


Magnetic Abrasive Finishing Week 7: AFM may be performed once, as a one-way flow process, or repeatedly as a two-way flow process.

In abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. Abrasive Flow Finishing Week 6: Introduction conventional abrasive processes,Introduction to abrasive processes,Grinding Process Amchining 2: Conventional abrasive finishing processes CAFP: Faculty who teaches manufacturing.
