Abstract :
Machining vibration is one of the main phenomenon occurs in milling of thin-walled workpiece, it will lead to poor surface finish and low machining efficiency. Especially for challenging situations such as large dimension closed casing, vibration is one of the main factors affecting the improvement of machining efficiency. In this work, a method by applying damping support fixtures for machining vibration suppression is developed. It can be mounted at different positions on the inner surface of casing to suppress vibration. This method has been validated by finite element simulation and cutting experiments. The results show that vibration can be suppressed with the presence of damping support fixtures. The new method can be used to get higher machining efficiency and better surface finish in milling of thin-walled casing.
