Effect of ultrasonic vibration on finished quality in ultrasonic vibration assisted micromilling of Inconel718

Ultrasonic Vibration Assisted Electro-Discharge Machining

An ultrasonic vibration has been superposed on the normal electrode movement to increase the flushing effect during a micro electro-discharge machining (EDM) process. A systematic study on the effects of ultrasonic vibration on the EDM performance for fabricating microholes in Nitinol has been completed. The introduction of ultrasonic vibration to the microEDM process has more than 60 times inc...

Influence of ultrasonic vibration on micro-extrusion.

Micro-forming is a miniaturization technology with great potential for high productivity. Some technical challenges, however, need to be addressed before micro-forming becomes a commercially viable manufacturing process. These challenges include severe tribological conditions, difficulty in achieving desired tolerances, and short tool-life due to inability of available die materials to withstan...

Effect of Ultrasonic Vibration on Proliferation of Cultured Cell

The effect of mechanical stimulation of vibration on proliferation of cells has been studied in vitro. To apply the vibration on the cells, a piezoelectric element was attached on the outside surface of the bottom of the culture plate of six wells. The piezoelectric element was vibrated by sinusoidal alternating voltage at 1.0 MHz generated by a function generator. Three kinds of cells were use...

Effect of Ultrasonic Vibration on Proliferation and Differentiation of Cells

The effect of mechanical stimulation of vibration on proliferation and differentiation of cells has been studied in vitro. To apply the vibration on the cells, a piezoelectric element was attached on the outside surface of the bottom of the culture plate of six wells. The piezoelectric element was vibrated by sinusoidally alternating voltage at 1.0 MHz generated by a function generator. Five ki...
