Parameters Optimization of Axial Vibration Drilling Based on the Exit Burr

Based on analyzing the mechanism of forming exit burr in drilling, the paper researches the process of forming exit burr in low frequency vibration drilling. The calculate formula of exit bun is achieved after calculate the force of axial and other forces in low frequency vibration drilling, which is also proved the reliability by the experiment. The parameters optimization method is available in order to reduce or mitigate the low frequency axial vibration drilling. It is lay a solid foundation for selecting the reasonable parameters of vibrating drilling process in the theory.
