It may be inevitable that the multi-edge rotary cutting tools such as drill, tap and reamer have a directional characteristics in the vibrational properties (that is, stiffness, natural frequency, damping coefficient), owing to the structure of the tools. In this research, the stability boundary of chatter is introduced theoretically as the function of the vibrational properties of the system and the various cutting conditions, and is ascertained experimentally. As a result, it has been shown that the chatter vibration of the multi-edge rotary cutting tool can be remarkably prevented through the good use of the directional characteristics of the system and the assigned combination of the setting angles of each cutting edge. Furthermore, it has been shown that there is the optimum tool configuration to prevent the chatter vibration.
