6.32. MACHINING CANNED CYCLES
This CNC features the following canned cycles:
G79 : User defined canned cycle
G81 : Drilling canned cycle
G82 : Drilling canned cycle with dwell
G83 : Deep drilling canned cycle
G84 : Tapping canned cycle
G85 : Reaming canned cycle
G86 : Boring canned cycle with G00 withdrawal
G87 : Rectangular pocket canned cycle
G88 : Circular pocket canned cycle
G89 : Boring canned cycle with G01 withdrawal
The canned cycles can be performed in any plane; so, when programming a canned cycle, it
will be performed in the plane selected, the penetration being carried out on the axis
perpendicular to that plane.
The fourth axis (W), as well as the 5th axis (V), can be a part of the main plane or, if they are
linear axes, they can be the perpendicular axis to this plane.
6.32.1. Zone of influence of the canned cycle
Once a canned cycle has been defined as described in the previous section, all the subsequent
blocks programmed will be under the influence of that canned cycle until it is cancelled. In
other words, each time a block is executed in which any movement of the axes is programmed,
the machining corresponding to the canned cycle defined will be carried out automatically.
The structure of the blocks which are within the zone of influence of the canned cycle is normal
except that N2 can be programmed at the end of the block (number of times the block is
repeated). If N0 is programmed, the canned cycle will not be performed after the movement
is carried out.
If there as a motionless block within the zone of influence of a canned cycle, the machining of
that canned cycle will not be carried out, except in the calling block. If continued performance
of the same canned cycle is desired with a change of any of the parameters (Z,I,J,K), the cycle
has to be redefined.
