摘　　要：在分析曲线插补原理的基础上,用最新的国际标准来表达曲线.以非均匀有理B样条为工具,利用NURBS强大的造型功能表示组合曲线,提出一种基于STEP-NC的非均匀有理B样条曲线插补方法.最后引入误差的控制,通过限定误差的大小来自动调节插补步长的大小,从而调节插补的速度,以达到高速高精度组合曲面加工的目的.To express the curve with the latest international standards on the basis of analyz the principle of the curve interpolation..A non - uni- form rational B- spline as a tool, use the powerful modeling capabilities of NURBS to express the combined curve, proposed a non - uniform rational B- spline curve interpolation method based on STEP - NC. At last lead into the error control,automatically adjust the size of the interpolation step through limit the size of the error to achieve the combination of high speed and precision surface processing purposes.
