To do this, the monotone curve is firstly drawn, and then without finding the coordinate of the inflexion point, 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；

The inflexion circle and Ball point were obtained under the finite approach state of mechanism movement position.

在机构运动位置的有限接近状态下，得到拐点圆及鲍尔点。

The point of minima value and the point of inflexion 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。

Konggur in Late Cenozoic; the inflexion of every elevation rise gradient may be the dividing point of different uplift process.

而每个抬升梯度的拐点，则对应着不同隆升过程形成海拔高度的分界点。
