Non Traditional Abrasive Machining Processes- Ultrasonic, Abrasive Jet and Abrasive Water Jet Machining

About the course

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

The lectures would introduce the basic principles of material removal by impact erosion by use of abrasives against hard and brittle materials. The technology of the manufacturing processes will be explained in detail. The machines used for USM, AJM and AWJM would be discussed. A variety of numerical problems would be solved. Material removal rates for the above processes would be worked out and effects of various input factors on the outputs of interest would be discussed.

MCQs, discussions will also be included.
