摘　　要：针对切削速度大幅度提高引发的铣刀安全性问题,主要介绍了高速铣刀安全性研究与设计的相关理论和方法.将高速铣刀安全性划分为安全稳定性和安全完整性两部分,指出在高速铣刀未发生完整性破坏之前,其安全性存在一个动态衰退过程,对相关的高速铣刀切削稳定性、刀具材料设计中的跨尺度关联、铣刀设计冲突与多层次功能耦合、铣刀设计与安全性评价中的不确定性等问题进行了分析和论述,提出高速铣刀安全性衰退机理与铣刀评价和整体优化设计应重点解决的关键问题.According to the cutter safety problem initiated by cutting speed raise substantially, this paper mainly introduces the relative theory and methods which research and design the safety of high speed milling cutter. The safety of high speed milling cutter is divided into safety stability stage and safety integrity stage. This paper points out a dynamic degenerative process before cutters lose efficacy in safety, meanwhile analysing and discuss on cutter with cutting stability, trans-seale design tool material, cutter design conflict and multi-level functional coupling and the uncertainty of design and safety evaluation. We put forward high-speed cutter safety recession mechanism to solve the key problems for the optimization design of whole high speed cutter.
