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...

We report on a newly-developed membrane stiffness-based separation of vesicles using a thermally-assisted acoustophoretic approach. By tuning the temperature, we achieved the separation of vesicles of the same size, shape, and charge but with different stiffness values. It was observed that at a specific transition point, the acoustic contrast factor of vesicles changed sign from positive to ne...

A hybrid-hybrid (ultrasonic-assisted + laser-assisted) turning study of silicon carbide reinforced aluminium metal matrix composite is presented. The results show a significant reduction average cutting force with an improved surface finish machined components compared to conventional machining, implying that this new and novel paradigm viable machining process.

Ultrasonic-assisted inner diameter machining is a slicing method for hard and brittle materials. During this process, the sawing force main factor affecting workpiece surface quality tool life. Therefore, based on indentation fracture mechanics, theoretical model of cutting an ultrasound-assisted saw established in paper improvement. The experiment was carried out with alumina ceramics (99%) as...
