By means of further analysis, solves the problem of the concentrated stress with magnifying arcradius and dividing the stress flow.
对此进一步分析，通过增大圆弧半径以及采取应力流分流的办法，最终解决这些应力集中问题。

The relation between the maximum radial error and arcradius and approach step-length in the secant mode of arc data interpolation in CNC system is detailed.
并讨论了圆弧分象限“均差”割线方式插补时，圆弧的起始步距角和终止步距角、起始象限步数和终止限步数；

The practice proves that by using the two measuring tools could directly measure the non-entire circle-arcradius, and the measuring tools are simply operated and economically used.
