User stock removal programs
15.3 Generate coded contour table (CONTDCON)
Further information
Permitted traversing commands, coordinate system
The following G groups and G commands can be used for the contour programming:
G group 1:
G group 10:
G group 11:
G group 13:
G group 14:
G group 15:
In addition, the following are possible:
● Rounding and chamfer
● Circle programming using CIP and CT
The spline, polynomial and thread functions result in errors.
Changes to the coordinate system by activating a frame are not permissible between
CONTDCON and EXECUTE. The same applies for a change between G70 and G71 or G700
and G710.
Replacing the geometry axes with GEOAX while preparing the contour table produces an
alarm.
Machining direction
The contour table generated using CONTDCON is used for stock removal in the programmed
direction of the contour.
