Machining Processes
GATE 2020
Easy
The process that uses a tapered horn to amplify and focus the mechanical energy for machining of glass is
- Aelectrochemical machining
- Belectrical discharge machining
- ultrasonic machining
- Dabrasive jet machining
Explanation
Ultrasonic Machining (USM) uses a tapered horn (concentrator/velocity transformer) to amplify a piezoelectric or magnetostrictive transducer's small-amplitude vibration into a larger-amplitude tool-tip motion, ideal for machining hard, brittle, non-conductive materials like glass.
