The distance criterion (= rounding clearance)
describes the maximum distance the rounding block may cover before
the end of the block, or the distance after the end of block within which
the rounding block must be terminated respectively.

If

clearance is automatically reduced (by up to 36%) for short traversing
distances.
: Continuous-path mode with smoothing within the defined tolerances
In this mode, under normal circumstances smoothing takes place
within the maximum permissible path deviation. However, instead of
these axis-specific tolerances, observation of the maximum contour
deviation (contour tolerance) or the maximum angular deviation of the
tool orientation (orientation tolerance) can be configured.
Note:
Expansion to include contour and orientation tolerance is only
supported on systems featuring the "Polynomial interpolation" option.

movements are inserted. The rounding clearance can be different for
each axis.
