Question

The process, that uses a tapered horn to amplify and focus the mechanical energy for machining of glass, is

Correct answer (C) ultrasonic machining Solution In Ultrasonic Machining (USM), a transducer converts electrical energy into high-frequency mechanical vibrations. These vibrations are transmitted to the tool through a tapered horn (also known as a concentrator or velocity transformer), which amplifies the vibration amplitude. This mechanical energy, combined with an abrasive slurry, is used to machine hard and brittle materials like glass. Turn this into a strength.
