Electrochemical and Electro-discharge machining (ECM and ED)}. 2. Mechanisms of Material Removal in USM and its modelling As has been mentioned earlier, USM is generally used for machining brittle work material. Material removal primarily occurs due to the indentation of the hard abrasive grits on the brittle work material.

19. ECONOMICS The process is economical when a large number of complex identical products need to be made (at least 50 units) . Several tools could be connected to a cassette to make many cavities simultaneously. (i.e. cylinder cavities in engines) . Large cavities are more economical on ECM and can be processed in 1/10 the time of EDM.
