segmented program

When measuring, based on the segmented contour line of thread, the measurement program to calculate and measure the geometrical parameters of internal taper thread is compiled. Precisions of pitch, thread angle and taper angle reach ± 0.03mm 、± 0.24 ° and ± 0.02 °.

使用自编程序测量计算了内螺纹的螺距、牙型角和锥角，测量精度分别达到了003mm，024°和002°。

This paper is based on the theory of accurate segmented catenaries calculation, adopts the method of modular design and uses Visual Basic 5.0 version to program codes to develop software, which accomplishes the corresponding functions of aerial cableway analysis and calculation.
