Micro-milling is one of important methods for producing miniature components with high-accuracy. During the cutting process, the chatter vibration which can result in instability and poor surface finish may considerably be disturbed by the unpredictable tool runout and centrifugal force with ultra high speeds of micro-mill. This paper tries to develop a time domain dynamic model for depicting chatter vibration of micro-mill with the concerns of tool runout incorporated in cutting forces and centrifugal force included in external force work via combing FEM and time-domain formulation. Several simulations carried out illustrates the validity of the proposed model from the perspectives of FRF, SLD and time domain response.

Bearing fit is closely related to the dynamic characteristics of the spindle system. When the spindle rotates at high speed, affected by centrifugal force, load and other factors, the bearing fit will change. In this paper, the finite element method is adopted. A dynamic model of motorized spindle is established to analyze the relationship between bearing clearance and bearing stiffness. Bearing stiffness directly affects the dynamic characteristics of the spindle rotor system. The machining accuracy of spindle system decreases with the increase of clearance amount. The establishment of dynamic model of motorized spindle provides theoretical guidance for structure design of motorized spindle.
