Study on Ultrasonic Vibration Cutting (3rd Report)

vibration cutting and elliptical ultrasonic vibration assisted turning of in738 work-pieces

vibration cutting (vc), elliptical vibration cutting (evc) and ordinary cutting (oc) of in738 work-pieces have been experimentally investigated in the present research. the experiments were carried out by using single crystal diamond tool and ultra-precision cnc lathe. vibration frequency is 36.16khz and the amplitude is . the influence of various cutting parameters including cutting speed, fee...

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...

Mirror Surface Finishing of Hardened Die Steel by High-power Ultrasonic Elliptical Vibration Cutting

Ultrasonic elliptical vibration cutting has recently been utilized in industry for finishing of various precision parts such as mirror surface finishing and precision micro machining of dies and molds. However, its application has been limited to high-cost ultra-precision machining, where depth of cut is typically in a range from a few micrometers to several tens of micrometers due to power lim...

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...
