曲面造型研究与程序开发

Study on the Modeling of Freeform Surface and Its Program Development

为了满足叶轮叶片类具有复杂曲面形状的零件的数控加工需求,文中以非均匀B样条为数学模型,应用Delphi5.0程序开发工具进行程序开发,分析了曲面造型的误差,并画出了直观的误差图,最后,将这一理论应用到叶轮叶片曲面造型之中。

For the needs of freeform surface like impeller and blade, this paper takes the Non-Uniform B_Splinc as a mathematical model, the programs are implemented in the integrated development environment Delphi 5.0, the error of B-Spline is analyzed, and the error distribution graph is drawing clearly, finally impeller and blade surface modeling is complenmented using B Spline.
