Certificate will have your name, photograph and the score in the final exam with the breakup. The lectures will introduce the basic principles of material removal by use of abrasives particles and material removal mechanism of different abrasive process.

NPTEL :: Mechanical Engineering – Advanced Manufacturing Processes

Retrieved from ” https: Conventional abrasive finishing processes CAFP: Grinding and lapping Metalworking. Final score will be calculated as: Abrasive particles in the fluid contact raised features fllow the surface of the workpiece and remove them. This course will define the areas of application of traditional as well as non-traditional abrasive finishing processes in the manufacturing industry.


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

Abrasive flow machining

This page was last edited on 25 Juneat 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. 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.

In abrasive flow machining, the abrasive fluid flows through the workpiece, effectively performing erosion. It will be e-verifiable at nptel. He has published over 30 research articles in internationally reputed journals, 2 Patents, 2 Edited Books and 6 Book chapters.

Introduction to Abrasive Machining and Finishing Processes

Faculty who teaches manufacturing. They may be manually operated, or automated using CNC.

Magnetic Abrasive Finishing Week 7: Manufacturing Engineering and Materials Processing. Abrasive flow machining was first patented by the Extrude Hone Corporation in The effects of various input parameters on the outputs as well as the use of cutting fluids in various finishing process will be discuss.


Abrasive Flow Finishing Week 6: Views Read Edit View history. 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.

Magnetic Rheological Finishing Week 8: 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. The fluid f,ow forced through the workpiece by a hydraulic ram[3] where it acts as a flexible nptwl, or slugmolding itself precisely to the shape of the workpiece.
