CRT 屏锥曲面测量造型关键技术研究

A Study of CRT Funnel Surface Measuring Modeling

根据我国新型阴极射线管（ＣＲＴ）的仿制需要，本文着重于ＣＲＴ屏锥曲面测量造型算法理论研究。通过Ｍ７６０三坐标测量机测得ＣＲＴ屏锥曲面数据后，提出了去掉测量数据坏点的预处理算法；采用数据匀化，消除了屏锥曲面局部病态，并给出屏锥曲面分块合理准则。基于ＣＲＴ屏锥曲面光顺概念和设计要求双重考虑，选用局部回弹光顺法，有效地解决了屏锥曲面的光顺问题。

This paper is put forward for the need of the funnel surface milling of a cathoderay tube(CRT). We apply measuring model technology to finish the funnel surface. The funnel surface bad parts are diminished, and the funnel surface smoothing is satisfied. Some main methods of the paper programmed in C++ language.
