6.32.4. G79. Canned cycle definition
By means of the function G79, the rank of canned cycle can be given to any parametric
subprogram defined by the user (G23 N2); that means the blocks following the calling block
(G79 N2 ...) are under the influence of the canned cycle until the function G79 is cancelled. The
calling block format is:
N4 G79 N2 P2=K— P2=K— ...
When reading a block programmed this way, the CNC will execute the N2 parametric
subprogram which will be identified by G23 N2 either in any part of the program or in another
program. In a calling block values may be assigned to the parameters (P2=K— P2=K—). If
after this block, any other movement of axes is programmed, N2 subprogram will be executed.
In the definition of a parametric subroutine (G23 N2) which is going to be called by the function
G79, no other canned cycle can be programmed. Otherwise the CNC will display error 13.
Nevertheless, G80 (end of canned cycle) can be programmed (must be by itself) in a block
indicating the end of the subroutine. If the subroutine has more than one nesting level, G80 can
only be programmed on the first level.
