A Research on Interpolation Algorithm of Space Line and Arc for Numerical Control System of Five-Axis Laser Cutting Machine
五轴联动激光切割机数控系统空间直线和圆弧插补算法的研究

Based on teaching function for generation of workpeice process program, this paper suggests an interpolation algorithm of space line and arc and the transformation of space absolute coordinates to machine motion coordinates. The interpolation error is also analyzed. This algorithm fulfills interpolation of space line and arc by controlling the motion of five axes simultaneously.
