The pointof minima value and the pointofinflexion are two common concepts of derivative.
极值点和拐点是高阶导数应用中两个常见的概念。

To do this, the monotone curve is firstly drawn, and then without finding the coordinate of the inflexionpoint, the NC machining path can be obtained by the method of automatic direction control.
首先对单调NC轨迹曲线进行绘制,进一步用不求极值点坐标而实现自动控制变向的方法,求出NC加工轨迹;
3
The inflexion circle and Ball point were obtained under the finite approach state of mechanism movement position.
