Review of dynamic issues in micro-end-milling

In recent years, the miniaturization of products has become a trend all over the world. Besides conventional precision manufacturing technology and micro-electro-mechanical systems (MEMS), micro/meso mechanical manufacturing (M⁴) technology is regarded as another choice for an effective method to fabricate micro complicated 3D features, which need special attention paid to. In micro-end-milling machining, the stiffness of a micro-end-milling machine tool is somewhat lower, due to the size effect of material, and also, obviously, the ploughing condition and the quite slender end-milling tool. Thus, the stability of a micro-end-milling machine is very weak. This paper reviews the state-of-the-art of studying chip formation and dynamic problems in micro-end-milling, and discusses the possible future works in this field.
