Regenerative chatter is a major factor restricting the process efficiency,process quality and the longevity of cutting tools in high speed turning.For the research of high speed turning process,the dynamic cutting force model and chatter stability domain analytical model were constructed,and the dynamic regenerative effects were taken into account.The machine-tool system frequency response function was obtained through modal testing.The analytical solution of the chatter stability domain was achieved by numerical analysis based on the above study,with integrated use of turning stability criterions.Furthermore,the time domain simulation on chatter stability of high speed turning was performed and the cutting force and tool tip displacement were obtained.The simulation experiment results show a good agreement with the analytical solution.Therefore,the correctness of chatter system dynamics model and chatter stability analytical model is validated.
