多年来，数控加工刀具轨迹的生成一直是制造工艺改进的主要课题。不同的方法试图将效率和最小的工具磨损与合理的计算时间结合起来。刀具路径的平滑曲率级数是限制所有轴上的抖动从而确保最小刀具磨损的主要要求。目前，这一要求是通过构造刀具轨迹的多项式或平滑较简单的线性和圆形曲线来满足的。本文提出了一种基于曲率光滑回旋线的插补方法。
The tool path trajectory generation for CNC machining has been a main topic in the improvement of the manufacturing process for many years. Different approaches tried to merge efficiency and minimal tool wear with reasonable computing times. A smooth curvature progression of the tool path is a main requirement to limit jerks in all axes and thus ensure minimal tool wear. Currently this requirement is met by constructing tool paths with polynomials or smoothing simpler linear and circular curves. This paper presents an alternative interpolation method based on curvature-smooth clothoids.
