High efficiency and superior performance are the trend for the development of the machine tools. One of the issues is the problem of cutting vibration. Chattering is a cause of cutting instability. Regarding to the chattering problem, lots of researches have been focused on the dynamic stiffness of the spindle of machine tool. In this research, the finite element method was used to analyze and compare the dynamic stiffness between a standard bearing-spindle system and a bearing-spindle grasps a long collet-chuck and cutter. The first model of vibration is usually caused by excessively length of the cutter or collet-chuck. In this research, machining stability theory by other researchers was referred. Computer simulation program was used to establish the range of stable cutting speeds. The result can be used to determine the operating parameters in design and manufacture. Furthermore, the data from frequency response measurement at tip of the cutting tool can be used to compare and contrast with finite element analysis result in order to find the ranges of cutting speeds which causes instability.
