空间自由曲面精度检验的精定位方法

Accurate-positioning methods of accuracy inspection for free-form surface

在空间自由曲面精度检验的自定位方法的基础上 ,提出了无定位基准的空间自由曲面精定位的基本思想。按工件坐标系的重合可通过几何元素的重合来达到的策略 ,导出了精定位的算法 。

Base on the self-positioning methods of accuracy inspection for free-form surface, this paper provides a basic idea of accurate-positioning methods of accuracy inspection for free-form surface. According to the tactics, which coincide of geometry element can instead of coincide of work coordinate system, this paper provides algorithm of accurate-positioning. All methods are realized with Turbo C.
