组合曲面的NURBS插补技术的研究

在分析组合曲面构成原理的基础上,将组合曲面分解为若干组合曲线,以非均匀有理B样条为工具,利用NURBS强大的造型功能表示分解得到的组合曲线,然后对组合曲线进行插补加工。通过对所有分解的曲线的加工达到加工曲面的目的,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。

Research on NURBS Interpolation of Combined surface

The combined surface is decomposed into a number of combination curve on the basis of analyz the principle of combined surface.A non-uniform rational B-spline as a tool,use the powerful modeling capabilities of NURBS to express the combined curve and then Interpolate it.Through the decomposition of the curve for all the processing to achieve the purpose of processing of surfaces.At last lead into the error control,automatically adjust the size of the interpolation step through limit the size of the error to...
