Ultrasonic machining (USM): principal metal removal mechanism In ultrasonic machining of hard/brittle materials, how is material removed from the work surface? Choose the correct mechanism.
Mechanical Engineering
Production Engineering
Difficulty: Easy
Choose an option
-
AAbrasive slurry between tool and work driven by ultrasonic vibration
-
BDirect continuous contact cutting by the hard tool edge
-
CElectrolytic dissolution in a small gap (electrochemical process)
-
DErosion by spark discharges across a gap (EDM)
Answer
Correct Answer: Abrasive slurry between tool and work driven by ultrasonic vibration
Explanation
ConceptUSM uses a vibrating tool to hammer abrasive grains (in a slurry) against the work, causing micro-chipping. It is mechanical erosion via abrasives, not direct cutting, electrolysis, or spark erosion.
Final AnswerAbrasive slurry between tool and work driven by ultrasonic vibration
