Working with contour-based cycles

Possibilities of transferring the contour to be machined to the cycle:
Transferring the contour reference in the Contour start block no.
and the Contour end block no.. The contour area is machined in
the direction from NS to NE
Transferring the contour reference via the name of the Auxiliary
contour (ID). The complete Auxiliary contour is machined in the
direction of contour definition
Describing the contour with G80 in the block directly after the
cycle
Further information:
Page 339
Describing the contour with G0, G1, G2 and G3 blocks directly
after the cycle. The contour is concluded by G80 without
parameters
Possibilities of defining the workpiece blank for calculating the
number of cutting passes:
Defining a global workpiece blank in the BLANK program section.
Regeneration of the workpiece blank is automatically active. The
cycle uses the specified Workpiece blank
If no global Workpiece blank is defined, the cycle calculates an
internal Workpiece blank based on the definition of parameter RH
