Technical Terms Ultra-Precision Machining: A manufacturing process characterised by extremely low tolerances and high surface quality, often achieving nanometre-level accuracy.

In brittle materials like engineering ceramics, abrasive grains are placed on the surface to machine away small fragments.

Electrical Discharge Machining (EDM) is being seen as a novel technique for surface modification. How the process works, problems associated with it, electrode materials, wear and corrosion resistant ...
