摘要：
For the special requirement of ultra-small micro-end mill for minimally invasive milling of bone tissue, the structural optimization design of special-shaped micro end mills is studied. Three kinds of micro-end mills (helical-shaped, △-shaped and □-shaped) with diameter of 50 μm were designed and manufactured, and their milling performances were also investigated. The geometric structures of micro-end mills with different shapes are analyzed, and the static analysis of the mills is conducted to study the effect of geometric structure of micro-end mill on its stiffness and strength. The precision milling method and milling quality of three kinds of micro-end mills are investigated. The bone tissue minimally invasive milling experiments using ultra-small micro end mills were carried out, and the morphologies of milled bone tissues were observed. The milling quality of bone tissue workpiece was analyzed. In the process of bone tissue micro milling, the helical-shaped micro-end mill is prematurely fractured, △- and □-shaped micro-end mills can cut for long time. For the △-shaped micro-end mill, the machined grooves have small burr width and edge collapse, and higher surface quality. The △-shaped micro-end mill is more suitable for minimally invasive milling of bone tissue. © 2020, Editorial Board of Acta Armamentarii. All right reserved.
