Withthe rapid development of numerical control techniques ,the production efficiency and product quality are in theli melight . However ,as millingis anintermittent process ,a periodic forceinteracts betweenthe cuttingtool andworkpiece which makes the chatter vibration developed at specific conditions .

| Abstract: | Modals of the machine/tool and machine/part system are the principal factors affecting the stability of a milling process. Based on the modeling of chatter stability of milling process,the influence of modal parameters on chatter stability lobes independently or jointly has been analyzed by simulation. Peak-to-valley specific value,lobe coefficient and the corresponding calculation formula have been put forward. General laws and steps of modal simplification for multimodality system have been summarized. |
