Abstract: Problems such as drill life exit burr and machined surface roughness etc. in-ultrasonic vibration drilling of micro holes are investigated Results show that ultrasonic vibration drilling is evidently superior to conventional drilling.

Key words: Drilling, Micro hole, Ultrasonic vibration, Mullins induced anisotropy, Multi-directional stiffness, Simulation, Elastic component, Rubber
