The limit formula of the critical grinding depth is calculated based on the dynamics model of the grinding chatter system. By applying this formula in the plunge grinding instance, the limit of the critical grinding depth is obtained. Finally, the validation experiments is carried out on the grinding machine and the results are consistent with the calculation. It testifies the validity of the calculation method and proves that the formula is quiet effective in practice.
