Parameters for B-SPLINE
The programmed restrictions (see A- or C-spline) do not have any affect on the B-spline. The
B spline is always tangential to the check polygon at its start and end points.
Point weight:
PW = n The weight details can be programmed as a so-called point-
weight (PW) for each interpolation point.
Value range:
<= n <= 3 in increments of 0.0001
Effect:
n > 1 The check point exerts more "force" on the curve.
n < 1 The check point exerts less "force" on the curve.
Spline degree:
SD = 2 A third degree polygon is used as standard, but a second
degree polygon is also possible.
Distance between nodes:
PL = value The distances between nodes are suitably calculated
internally. The control can also machine predefined node
distances that are specified in the so-called parameter-
interval-length (PL).
Value Value range as for path dimension
