五轴铣床的逆运动学在所需曲面的固定点附近产生大的误差。当工具穿过或围绕该点行进时，旋转角度可能显著跳跃，从而导致与规定轨迹的意外偏差。我们提出了两种新的算法来修复的轨迹，通过调整旋转角度的方式，运动学误差最小化。角度切换算法计算所有可行的旋转，并通过最短路径方案确定优化的旋转序列。进一步减少误差的角度插入算法的基础上应用于旋转附近的奇异性的均匀分布的原则。我们已经验证了算法的两个五轴铣床，即MAHO 600 E在CIM实验室的亚洲理工学院和HERMLE UWF 920 H在CIM实验室的Kasetsart大学。
The inverse kinematics of five-axis milling machines produces large errors near stationary points of the required surface. When the tool travels across or around the point the rotation angles may jump considerably leading to unexpected deviations from the prescribed trajectories. We propose two new algorithms to repair the trajectories by adjusting the rotation angles in such a way that the kinematics error is minimized. The angle switching algorithm computes all feasible rotations and identifies an optimized sequence of rotations by the shortest path scheme. Further error reduction is accomplished by the angle insertion algorithm based on the equi distribution principle applied to rotations near the singularity. We have verified the algorithms by two five-axis milling machines, namely, MAHO600E at the CIM Lab of Asian Institute of Technology and HERMLE UWF920H at the CIM Lab of Kasetsart University.
