Definitions: Transducer and sensors • Transducer – a device that converts a primary form of energy in to a corresponding signal with a different energy form Primary Energy Forms: mechanical, thermal, electromagnetic, optical, chemical, etc. Capacitive transducers (source: directindustry.com) Capacitive Transducers Contents hide 1. Introduction • Ultrasonic machining is a mechanical type non-traditional machining process employed to machine hard and brittle materials (both electrically conductive and non conductive material) using an axially oscillating tool at ultrasonic frequencies [18–25 kilohertz (kHz)].
