5.5 Smoothing the path velocity
Function
A smoother path velocity profile can be achieved with the "Path velocity smoothing" function,
which allows special, configurable, machine data and the character of the parts program to
be taken into account.
The velocity control function utilizes the specified axial dynamic response. If the programmed
feedrate cannot be achieved, the path velocity is brought to the parameterized axial limit
values and the limit values of the path (velocity, acceleration, jerk). This can lead to repeated
braking and acceleration on the path.
Note
Machine manufacturer
The user can control the path velocity as appropriate for the configurable machine data by
making use of the program properties.
