Always in line contour table end (forwards) +1:
5) Predecessor: Number of relief cuts (forwards)
6) Successor: Number of relief cuts (backwards)
Once each within the contour elements backwards:
7) Successor: Contour end (backwards)
8) Predecessor: Contour start (backwards)
Always in last line of table:
9) Predecessor: Line n is the contour table start (backwards)
10) Successor: Line n contains the contour start (backwards)
Further Information
Permitted traversing commands, coordinate system
The following G commands can be used for the contour programming:
● G group 1:
In addition, the following are possible:
● Rounding and chamfer
● Circle programming using
The spline, polynomial and thread functions result in errors.
Changes to the coordinate system by activating a frame are not permissible between

Relief cut elements
The contour description for the individual relief cut elements can be performed either in a
subprogram or in individual blocks.
Stock removal independent of the programmed contour direction
The contour preparation with
contour table is available independent of the programmed direction.
