APC to reduce machining-related oscillation

Function description
The "APC function to reduce machining-related oscillation" allows this type of oscillation to be
specifically dampened.
General data
● The function is especially suitable for axes equipped with linear motors.
● The function can be used in addition to other APC functions.
● A direct measuring system is not required.
Machining-related oscillation
Machining-related oscillation involves mechanical oscillation, which require a special method
to dampen them. An important attribute is that machining-related oscillation only has a very low
feedback in the speed control loop and/or in the frequency domain. However, in the time
domain their effects can be clearly measured.
Note
Machining-related oscillation has an especially negative impact on the control behavior of axes.
