【Abstract】 Based on the principle of pattern recogniton and the dynamic characteristics of the cutting process, a pattern vector plane is established for showing the stability of the cutting process. The movement of the end of pattern vector on the plane indicates the variation of the stability during cutting. A criterion for early diagnosis of chattering and a control strategy as well as an experimental on-line monitored control are described.更多还原
