The nanosize FTO was self-synthesized by using raw materials of tin oxide pentahydrate and ammonium fluoride by following the previous method [9].
This were mainly due to the high surface area, well dispersed of metal cluster on the FTO as well as of its amphoteric materials properties.

As the changes in cutting speed and the emergence of acceleration, it makes power ultrasonic vibration cutting obtain better results than the traditional cutting in difficult to machine materials and ordinary materials processing of the difficult processing operations.However, the power ultrasonic vibration cutting mechanism remains to be explored further, in particular variation of cutting temperature.
Heat transfer between them change with the workpiece material, tool material, cutting parameters and tool geometry.
The parameters are Rake angle is 5.0deg, Rake Length is 2.0mm, Relif length is 2.0mm, the tool material is Diamond, the workpiece material is 300M-steel.
