Question

Ceramics and glass are machined by

Correct answer (B) ultrasonic machining Solution Machining of ceramics and glass: Electric Discharge Machining (EDM) : Requires the workpiece to be electrically conductive. Ceramics and glass are generally insulators. Electrochemical Machining (ECM) : Also requires electrical conductivity. Plasma Machining : Uses high-temperature plasma, primarily for metals. Ultrasonic Machining (USM) : Uses high-frequency vibrations and abrasive slurry to erode material. It is highly effective for hard, brittle, and non-conductive materials like ceramics and glass.
