Hence, for approximate calculations, VA can be ignored as compared to Vh. BIBLIOGRAPHY 1. 2. 3. Bellows G. B. (1982), Drilling W ithout Drills, American Spe­ cial Report, 743, p. 187. F. , New York.

A brittle material can be machined more easily than a ductile one. It is considered as a very safe process because it does not involve high volt­ age, chemicals, mechanical forces and heat. 4 kW. USM system has sub-systems as power supply, transducer, tool holder, tool, and abrasives. High power sine wave generator converts low frequency (60 Hz) electrical power to high frequency (=20 kHz) electrical power. This high frequency electri­ cal signal is transmitted to the transducer which converts it into high frequency low amplitude vibration.
