Applying the concept of relative cutting velocity, the expression of velocity type dynamic cutting force and the mechanics model of chatter vibration in turning or boring process were advanced.
The turning rate is calculated at each step from the velocity and acceleration estimates of interacting output as the magnitude of the acceleration divided by the speed of the target.
每一步通过交互输出的速度和加速度的估计值来计算转弯速率，它的大小等于加速度和速度的比值。

Based on the tests of angular velocity, the turning Angle and the accuracy of solar orientation, this auto-tracking system was proved effective.
