Rotationally symmetric blank of any shape
You define the contour of the rotationally symmetric blank in a
subprogram. Use X, Y or Z as the rotation axis.
In the workpiece blank definition you refer to the contour
description:
DIM_D, DIM-R: Diameter or radius of the rotationally
symmetrical blank form
LBL: Subprogram with the contour description
The contour description may contain negative values in the rotation
axis but only positive values in the reference axis. The contour
must be closed, i.e. the contour beginning corresponds to the
contour end.
The subprogram can be designated with a number,
an alphanumeric name, or a QS parameter.
