| 摘 要： | 在模具计算机辅助设计以及其他工业设计领域中，曲线的等距放大功能运用十分普遍，如常见的编制数控加工指令，冲模的凸凹模间隙处理等。平面直线、圆弧组成的线条族的等距放大问题已经在很多文献中给出比较完善的解决方案，技术相对比较成熟，而平面上自由曲线的等距放大问题却没有很好的解决方案。本文就有理B样条的等距放大问题给出一个比较实用的解决算法。

| Abstract: | In the die and mould CAD field and other industry design field, theoffsetting of curve are used widely, such as the NC programming, and dealingwith the clearance of die. The offsetting of line and arc have been well discussed in many thesises, and many skilled methods were given, but very few forthe offSetting of the free curve. So, a useful solution for NURBS curve is givenin this paper. |
