Abstract
- This paper presents a comprehensive model for the motorized spindles in machine tools. The proposed model consists of a thermo-mechanical dynamic model and a milling stability model. The thermo-mechanical dynamic model is establishedbased on finite element method with the consideration of the transfer function at cutting point, which is coupled with the milling stability model. The influences of thermo-mechanical coupled factors (TMCF) on the transfer function at the cutting point and the milling stability of the system are discussed and validated, and the influences of the parameters of the material properties and machining process on the milling stability are acquired. The theoretical and experimental results are useful to the dynamic analysis and design for motorized spindle machine tools. [ABSTRACT FROM AUTHOR]
