Description:

Ultrasonic assisted drilling is a recently-developed technique, in which high-frequency (> 20 kHz) vibration is superimposed onto the movement of a standard drill bit in the axial direction, providing advantages including reduced drilling forces (reduction often in excess of 80%) and improved quality of drilled holes when compared to conventional drilling. Ultrasonic assisted drilling also achieves a reduction in entry and exit delamination size, but not in the expected proportion considering the observed reduction of drilling forces. A different mechanical process to that in conventional drilling may be driving the delamination in Ultrasonic assisted drilling, for example dynamic or thermal effects in addition to thrust and torque loads.

The aim of this project is to achieve a mechanical understanding of the process that drives delamination during Ultrasonic assisted drilling and to implement it in an analytical model and numerical tools with predictive ability. These can then be used to enhance Ultrasonic assisted drilling to minimise delamination and to predict the performance of hybrid joints with Ultrasonic assisted drilling-induced damage.

Application:

1. Various kinds of materials especially fragile rigid material.

2. Processing plane, groove, all kinds of form surface (such as spline, gear and thread) and special surface of mould.

3. Application area: machining industry, machine tool equipment manufacturing.

4. Application occasion: manufacturing enterprise, universities and colleges, scientific research institution, mechanical equipment transformation industry.

Advantage:

· Virtually any hard material can be machined

· Little heat is produced

· Since the motion of the tool is up-and-down vibration rather than rotation as in traditional machining, the holes cut are not limited to circular shapes but can be any shape. Custom "cookie cutter" tools can cut complicated shapes.

· Good surface finish and higher structural integrity is obtained
