Influence zone of a canned cycle
9.2 Influence zone of a canned cycle
Once a canned cycle has been defined it remains active, and all blocks programmed after this block
are under its influence while it is not cancelled.
In other words, every time a block is executed in which some axis movement has been programmed,
the CNC will carry out (following the programmed movement) the machining operation which
corresponds to the active canned cycle.
If, in a movement block within the area of influence of a canned cycle, the number of times a block
is executed (repetitions) "N" is programmed at the end of the block, the CNC repeats the
programmed positioning and the machining operation corresponding to the canned cycle the
indicated number of times.
If a number of repetitions (times) "N0" is programmed, the machining operation corresponding to
the canned cycle will not be performed. The CNC will only carry out the programmed movement.
If, within the area of influence of a canned cycle, there is a block which does not contain any
movement, the machining operation corresponding to the defined canned cycle will not be
performed, except in the calling block.
G81... Definition and execution of the canned cycle (drilling).
G90 G1 X100 The X axis moves to X100, where the hole is to be drilled.
G91 X10 N3 The CNC runs the following operation 3 times.
• Incremental move to X10.
• Runs the cycle defined above.
G91 X20 N0 Incremental move only to X20 (no drilling).
