Title: Some Considerations on Prevention of Chatter Vibration in Multi-Edge Rotary Cutting Tool (Continued)
Abstract: The stability boundary of chatter vibration occurring in the multi-edge rotary cutting tool is examined from a practical point of view. As a result, it has been shown that (1) the chatter vibration can be prevented through a good use of the directional characteristics of the system and a proper combination of the setting angles of each cutting edge, in the multi-edge rotary cutting tool with 2, 3 or 4 cutting edges ; and (2) there is an optimum tool configuration to prevent the chatter vibration, and this configuration is not affected by the number of the cutting edges and the setting angles of each cutting edge. Furthermore, the effect of a small error in the tool setting condition and in the tool dimensions (such as cutting angle, nose radius etc.) is studied for many practical cases.
