The Effect of Impeller Machining Allowance Changes on the Milling Chatter Stability Lobes

The impeller has many characteristics, such as having thin wall, low rigidity, the quality of time-varying and it easy to produce deformation and vibration in process. In order to predict the flutter during processing, milling system dynamics model is established first, and then research three-dimensional flutter stability lobes of milling system by the fully discrete method. Finally analyzes the impeller machining allowance change on the influence of the flutter stability lobes and the milling parameters on the stability of the milling system dynamics.
