Fixed Cycles: Contour Pocket | CONTOUR TRAIN (Cycle 25, DIN/ISO: G125, software option 19)

Please note while programming:

The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
The TNC takes only the first label of Cycle 14 CONTOUR
into account.
The sub program allows no APPR or DEP motions.
When you use local QL Q parameters in a contour
subprogram you must also assign or calculate these in
the contour subprogram.
The memory capacity for programming an SL cycle is
limited. You can program up to 16384 contour elements
in one SL cycle.
Cycle 20 CONTOUR DATA is not required.
If M110 is activated during operation, the feed rate
of compensated circular arcs within will be reduced
accordingly.
Danger of collision!
If you set the parameter posAfterContPocket to
ToolAxClearanceHeight, the TNC positions the tool after the end
of the cycle only in the tool axis direction to the clearance height.
The TNC does not position the tool in the working plane.
After the end of the cycle, position the tool with all
coordinates of the working plane, e.g.
After the cycle, program the absolute position (not an
incremental traversing movement)
