摘要: 在示教生成零件加工程序的基础上,讨论了空间直线和圆弧的插补算法以及空间绝对坐 标到机床运动坐标的变换,并对插补算法的误差进行了分析.这种插补算法通过控制五个联 动的运动轴,可实现空间任意直线和圆弧的插补,从而在理论上使激光切割机能完成对空间 曲面的切割加工.Abstract: 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.
