Abstract

Chatter vibrations limit machining productivity and sometimes result in reduction of tool life in the end-milling process. There are two major types of chatter vibrations, i.e., forced and self-excited types. Their generation mechanics are different, and thus their characteristics and strategies to avoid them are also different. It is, therefore, needed in practice to understand their relationship and to select efficient milling conditions to stabilize the process for the self-excited chatter vibration and to minimize the forced chatter vibration at the same time. However, most of past research works have been focused only on the self-excited chatter vibration, and detailed analysis of the forced chatter vibration and its relationship to the self-excited chatter vibration can not be found in the literature. Thus, an analytical model of the end milling process with the forced chatter vibration is developed and verified experimentally. Then, the characteristics of the forced type and its relationship to the self-excited type are clarified, and the milling conditions to avoid the both types are clarified by utilizing the analytical model developed here and the model of the self-excited type developed in the past research.
