In this paper, simulated results of the dynamic cutting process in end milling are described based on the multi-degree of freedom model for machining center spindle system. The spindle system is represented by the three degree of freedom system that consists of spindle, tool holder and tool. The dynamic characteristics such as mass, stiffness and damping of the spindle system are modified and the equations of motion for end milling are solved to clarify the influence of those parameters on the chatter stability. The results show that the chatter stability is influenced by the mode coupling of tool and tool holder and then the stiffness and/or damping of both tool and tool holder greatly dominate the chatter stability at higher spindle speed range.
