Siemens shaft impact limiting function

In some applications, such as milling the surface of any shape, it may be very effective to smooth the change of the position setting value of the machine tool axis with the help of the axis impact limiting filter, so as to reduce the mechanical vibration on the machine tool and obtain higher workpiece surface quality. The filtering effect of the position setting value must be enhanced as much as possible without affecting the contour accuracy. In addition, the smooth effect of "symmetry" should be achieved as much as possible. In other words, if the same contour is run forward or backward, the contour curve smoothed by the filter should be as similar as possible in both directions.

The filtering effect of axis impact limit will have a slight impact on the position setting value and reduce the trajectory accuracy to a certain extent. We can observe the effect of the filter through the effective kV coefficient displayed in the "axis information" window. Generally speaking, as the filter time increases, the effective kV coefficient displayed on the system will gradually decrease.
