Syntax
General:
ASPLINE X... Y... Z... A... B... C...
BSPLINE X... Y... Z... A... B... C...
CSPLINE X... Y... Z... A... B... C...
For a B spline, the following can be additionally programmed:
PW=<n>
SD=2
PL=<value>
For A and C splines, the following can be additionally programmed:
BAUTO / BNAT / BTAN
EAUTO / ENAT / ETAN
Significance
Spline interpolation type:
ASPLINE
Command to activate A spline interpolation
BSPLINE
Command to activate B spline interpolation
CSPLINE
Command to activate C spline interpolation
The
ASPLINE, BSPLINE and CSPLINE commands are modally effective
and belong to the group of motion commands.
Points along a curve and check points:
X... Y... Z...
A... B... C...
Positions in Cartesian coordinates
Point weight (only B spline):
PW
Using the
PW command, a so-called "point weight" can be
programmed for every point along the curve.
"Point weight"
Range of values: 0 ≤ n ≤ 3
Increment: 0.0001
n > 1 The checkpoint attracts the curve
more significantly.
<n>
Effect:
n < 1 The checkpoint attracts the curve
less significantly.
Spline degree (only B spline):
SD
A third degree polygon is used as standard, However, a second
degree polygon can also be used by programming
SD=2.
