摘要：Semi-discretization method is expanded to determine the stability charts of NFDE for milling processes including process damping. The method is based on a special kind of discretization technique with respect to the past effect only. The convergence of approximate method is investigated by the example of delayed Mathieu equation, and stability charts of the damped and neutral delayed Mathieu equation for different time-period/time delay ratios are determined. The results show that, semi-discretization method can be employed to predict the stability of milling processes including process damping. ©2010 IEEE.
