Canned cycle II (Counter boring cycle)
The spindle orientation stop is performed after the X and Y axes are positioned. The tool is offset
and positioned to the bottom of the hole (Point R) at the rapid traverse rate in the direction of the
reverse tool nose. The tool returns based upon the original offset amount, and starts the spindle CW;
it is machined to the Point Z along with the Z axis. The dwell does not perform if the P command
occurs, in this position, the tool retracts to the original offset value after the spindle is orientated to
stop again and move to the upper hole. The tool is then returned to the origin or based upon the
original offset amount, the spindle rotates positive to the next block. The offset amount and direction
of the X and Y axes are absolutely same with the G76.
Note: Canned cycle I
It is set by parameter 009 BIT7 (FIX2); signal SRV and SSP are separately regarded as the output
signal of the spindle negative and spindle stop.
Canned cycle II:
It is set by parameter 009 BIT7 (FIX2); M code is treated as the output signal of the spindle reverse,
spindle stop and spindle orientation stop.
(12) G88 (Boring cycle)
G88 (G98) G88 (G99)
This command is same with the G87 (Canned cycle I) other than the spindle stops after dwelling
at the bottom of the hole.
(13) G89 (Boring cycle)
