This paper presents a new technology to realize high-efficiency, smooth-surface, and high-chatter-stability machining of flexible thin plates with the proposed face-milling cutter geometry. Radius end mills are widely utilized for high-efficiency and smooth-surface machining, but they generally have low machining stability, i.e. chatter vibrations often occur. It is well known that the chatter stability depends on the structural flexibility and the cutting conditions, whereas it is less known that it strongly depends on the cutter geometry. In this study, a novel face-milling cutter geometry is proposed to improve chatter stability, especially for regenerative chatter, without sacrificing the high efficiency and the surface smoothness in radius end milling. The validity of the milling technology utilizing the proposed cutter geometry is verified analytically and experimentally.

本文提出了一种新技术，可以利用提出的平面铣刀几何形状实现对柔性薄板的高效，光滑表面和高颤动稳定性的加工。半径立铣刀广泛用于高效和光滑表面加工，但是它们通常具有较低的加工稳定性，即经常发生颤振。众所周知，颤振的稳定性取决于结构的柔韧性和切削条件，而鲜为人知的是，其强烈取决于切削刀具的几何形状。在这项研究中，提出了一种新颖的平面铣刀几何形状，以改善颤振稳定性，特别是对于再生颤振，而又不牺牲半径立铣刀的高效性和表面光滑度。
