A study on the Evaluation for the Static and Dynamic stiffness of a Machining Center

머시닝 센터의 정${\cdot}$동강성 평가에 관한 연구

A machining center is a complex dynamic system whose behavior influences the machining stability and machined surface quality. This paper focused on establishment of a measurement system and experimental study on static, dynamic, and modal analysis of a machining center. The dynamic stiffness result by the analysis showed the weak part of the machining center. The results provided structure modification data for getting better dynamic behaviors.
