摘　　要：国内外对五轴数控加工中的扫掠轮廓线的研究往往集中于主轴摆动式机床。本文给出了实际生产中应用广泛的工作台旋转式五轴加工中环形刀具上扫掠轮廓线的显式表达式,分析了扫掠轮廓线在刀具曲面上的几何特性。所用的计算方法高效精确,为复杂曲面加工过程的动态模拟和加工误差的控制奠定了数学基础。The study of the swept profile in 5-axis machining was always focused on a spindle type of machine. The paper presents an explicit representation of the profile for a table rotation type of 5-axis machining, which is widely used in industry, with a fillet-end cutter. The geometric shape and characterization of the profile are fully analysed on the cutter surface. The method is efficient and precise, and lays a mathematic foundation for NC verification and machining error control in 5-axis sculptured surface manufacturing.
