Ultrasonic machining (USM) is a non-traditional machining process that uses vibrations and an abrasive slurry to remove material from a workpiece. It's a subtractive manufacturing process that uses high frequency, low amplitude vibrations to remove material from the surface of a part. USM is a non-thermal process that's good for intricate and fragile materials. It uses less heat than other machining processes. USM uses a tool that vibrates perpendicular to the workpiece at a frequency above the audible range. The tool removes material by abrading it with a grit-loaded liquid slurry that... Show more Ultrasonic machining (USM) is a non-traditional machining process that uses vibrations and an abrasive slurry to remove material from a workpiece. It's a subtractive manufacturing process that uses high frequency, low amplitude vibrations to remove material from the surface of a part. USM is a non-thermal process that's good for intricate and fragile materials. It uses less heat than other machining processes. USM uses a tool that vibrates perpendicular to the workpiece at a frequency above the audible range. The tool removes material by abrading it with a grit-loaded liquid slurry that circulates between the workpiece and the tool. The best material for USM is medium tough steel, which offers the best compromise between cutting rate and tool wear. The material used for the USM tool must be ductile and strong. Some disadvantages of USM are: It's slower than other mechanical processes. Tool wear is high because abrasive particles affect both the workpiece and the tool. It can only machine hard materials. For example, it can't machine ductile metal. Related Test: Manufacturing Engineering Practice Test: Ultrasonic Machining Show less
