| Popis: | Coupled torsional-axial vibration of the drilling tool plays a significant role in the machining dynamics of the drilling process. This paper models the torsional-axial vibration of the drilling tool due to the warping deformation of the pretwisted flute. The warping-dependent cross-sectional properties of the drill flute are obtained from 2D finite element method. Natural frequency and mode shape corresponding to the torsional-axial vibration of the drill are predicted. The effects of helix angle, web thickness, and aspect ratio on the coupled torsional-axial dynamics are analyzed for conventional and micro drilling. The simulations are validated by experimental results using modal testing technique. The proposed model is able to provide guidance in selecting geometric configuration of the drilling tool for required torsional-axial dynamic behavior with high computational efficiency and guide the drilling process in order to reach desired hole quality. |
