摘　　要：提出一种显式表达主轴摆动式五轴数控加工中环形刀具上扫掠轮廓线的算法。运用包络原理,推导出扫掠轮廓线的计算公式。并在此基础上,分析了轮廓线在刀具曲面不同部分的形状及几何性质,列举了轮廓线各种可能性。进而,根据线动成面的原理,构造并显示了刀具扫掠面。实例表明,所提出的计算方法高效精确,为复杂曲面五轴加工过程的动态模拟和加工误差的控制奠定了数学基础。This paper presents a method to explicitly represent the swept profile for the spindle rotation type of 5-axis machining. In terms of envelope theory, the mathematical formulation of the profile is derived for a fillet-end cutter. Based on that, geometric shapes and characteristics of the profile are fully analyzed on the different parts of the cutter. Furthermore, possible cases of the profile are enumerated and the cutter swept surface is constructed. Simulated examples show that the presented method is efficient and precise. The method also lays a foundation for NC verification and machining error control in 5-axis machining.
