三维直线插补算法的优化及精度分析

Analysis of optimization and precision on 3D-line interpolation

优化了最小偏差三维直线插补算法,并在最小偏差法二维直线插补精度不大于半个脉冲当量的基础上,首次采用解析法证明了最小偏差法三维直线插补精度,并用实例进行了验证。为三维直线插补算法的广泛应用奠定了理论基础。

3D-line interpolation of little deviation is optimizated and its precision of little deviation is proved for the first time by analytical geometry on the basis of 2D-line interpolation precision. Case study indicates its performance, which lays the theoretical foundation for the wide of 3D-line interpolation.
