Notes
This is a global parameter. The value set here applies to all axes and
processes.
Function
This parameter limits the amount of automatic feedrate reduction that
occurs under certain compensation conditions.
When cutting along the inside of a circular path with cutter compensation
active, the actual compensated path covers less distance than the
programmed path. As a result, the control automatically reduces the
feedrate as much as necessary to maintain a constant cutting feedrate (tool
tip relative to point of contact on the workpiece).
This parameter sets a minimum to that feedrate reduction. The value
entered here is the minimum percentage of the programmed feedrate that is
allowed.
If 100% is entered here, it effectively disables automatic feedrate reduction
during cutter compensation.
This is not a per-axis parameter. The value selected here is applied to all
axes and processes.
