Ultrasonic vibration machining allows extremely complex and non-uniform shapes to be cut into the workpiece with extremely high precision. [ 4 ] Machining time depends on the workpiece's strength, hardness , porosity and fracture toughness ; the slurry's material and particle size; and the amplitude of the sonotrode's vibration. [ 4 ]
The Ultrasonic/Sonic Driller/Corer (USDC) is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the material.
A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.
Ultrasonic horns of this type are used primarily as parts of various ultrasonic instruments for ultrasonic welding, ultrasonic soldering, cutting, making surgical tools, molten metal treatment, etc. Converging ultrasonic horns are also commonly included in laboratory liquid processors used for a variety of process studies, including ...
Ultrasonic Consolidation (UC) or Ultrasonic Additive Manufacturing (UAM) is a low temperature additive manufacturing or 3D printing technique for metals. [ 1 ] UAM part examples: Micro heat exchanger and dissimilar metal part with aluminum and copper.
By adjusting the ultrasonic frequency of the device, it is possible to cut hard tissue while leaving soft tissue untouched by the process. The ultrasonic frequency is modulated from 10, 30, and 60 cycles/s (Hz) to 29 kHz. The low frequency enables cutting of mineralized structures, not soft tissue.
Jeremy Clarkson has shared a health update just months after the former Top Gear host underwent urgent live-saving surgery on his heart in October. The Clarkson’s Farm host, who recently cut his ...
Ultrasonic impact treatment (UIT) is a metallurgical processing technique, similar to work hardening, in which ultrasonic energy is applied to a metal object. This technique is part of the High Frequency Mechanical Impact (HFMI) processes. Other acronyms are also equivalent: Ultrasonic Needle Peening (UNP), Ultrasonic Peening (UP).
