Analysis of the Vibration Mechanism in the Turn-Milling Machining of Micro-Miniature Shafts

Article Preview

Abstract:

The vibration phenomenon appeared in orthogonal experiments of turn-milling machining of micro-miniature shafts. In order to study the causes and conditions of vibration, the vibration test experiment system was established and frequency spectrum analysis of acquisition data was done. The results show that its machining vibration is caused by the low-frequency flutter of the milling spindle. And the coupling relationship of the micro-miniature shaft and the turning spindle was discussed with FEM. The results show that the vibration of the micro-miniature shaft does not affect the vibration of the turning spindle, while the vibration of the turning spindle can cause the vibration of the micro-miniature in their low order vibration mode.
