###### An Analysis and Modeling of the Dynamic Stability of the Cutting Process Against Self-Excited Vibration

dynamic equations of the system consisting of 8 equations varying with time and space are solved using the method of separation of variables with respect to time and space. The dynamic effect of the temporal term appears in these equations in the form of a frequency term. By eliminating the temporal dependence from dynamic equations governing the behavior of the system, we arrive at 8 spatial equations for positions along the beam, which can be solved by applying boundary constraints (conditions) with respect to space, as shown in Figure 4.2a . Figure 2 The
