A study on natural vibration characteristics of small and high speed spindle system with a long work piece

세장비(細長比)가 큰 가공 소재를 포함한 소형 고속 스핀들 시스템의 고유진동 특성 연구

Modal analysis is an important and essential process in design of a high speed machining center. Generally, modal analysis of a built-in spindle system has not taken the work piece's shape and dimension into consideration. Since small and long work pieces influence greatly the natural frequency of the entire system, the high speed spindle system which continuously makes small machine parts by long work pieces for improvement of machining time has to consider the machining work pieces. Therefore frequency characteristics of the spindle system with long work pieces are studied in this paper.
