Paper Title:
Failure Mechanism of Twist Drill in Vibration Drilling of Duralumin
  Abstract

Based on experiments of common drilling and vibration drilling on duralumin (2A12), the failure mode and failure reason of twist drill are studied theoretically and experimentally. The result shows that, compared with common drilling, the wear of clearance face and rake face decreases evidently during vibration drilling, and the wear of chisel edge and marginal point of twist drill hardly happens. Moreover the probability of drill breakage is very low during vibration drilling. However, if amplitude is bigger, the tipping of chisel edge often appears.
