2.17.1 Detailed description
2.17.1.1 General information
Key statement
In certain application scenarios, e.g., when milling free-form surfaces, it may be beneficial to
smooth the position setpoint characteristics of the machine axes. This enables surface
quality to be improved by reducing the mechanical vibrations generated in the machine.
For the purpose of smoothing the position setpoint characteristic of a machine axis, a jerk
filter can be activated at position controller level, independently of the channel- and axis-
specific jerk limitations taken into account at interpolator level.
The effect of the jerk filter must be as strong as possible without having an unacceptable
impact on contour accuracy. The filter should also have as "balanced" a smoothing effect as
possible, i.e., if the same contour is traversed forwards and backwards, the contour
smoothed by the filter should be as similar as possible in both directions.
