The Crusader II's Z-axis canned cycles are similar to the X & Y axis canned cycles except for one important point:
the canned cycle is activated each time the spindle moves to a new location, until canceled by G80 command.
The Crusader II's Z-axis canned cycles include the following:
The G81 single stroke drill canned cycle will:
a) rapid down to clearance plane,
b) feed to final depth, then
c) rapid out to clearance plane.
Variable useage is as follows:

The G82 canned cycle is the same as the G81 canned cycle except that it has a timed dwell at depth
that is useful for countersinking and counterboring.
The G82 drill canned cycle will:
a) rapid down to clearance plane,
b) feed to final depth, and
b) hold at the final depth for a specific number of seconds, then
c) rapid out to clearance plane.

The G83 canned cycle is the same as the G81 canned cycle except that it will "peck" the hole and completely withdraw from the hole each peck increment until the final drill depth has been reached.
The G83 Peck Drill canned cycle will:
a) rapid down to clearance plane,
b) feed in 1st peck increment,
b) rapid out,
c) rapid back in,
d) feed in next peck increment,
e) rapid out,
f) rapid back in,
g) feed in next peck increment,
etc. until the final depth has been reached.

The G85 bore cycle canned cycle is the same as the G81 single stroke drill canned cycle except that it feeds in and feed out.
The G85 bore cycle will:
a) rapid down to clearance plane,
b) feed in to depth,
c) feed back out.

The G86 Bore-in-One-Direction cycle canned cycle is the same as the G81 single stroke drill canned cycle except for program stops at top and bottom of Z-stroke. This cycle backs off the tool to avoid retracting tool marks.
The G86 Bore-in-One Direction canned cycle will:
a) rapid down to clearance plane,
b) feed in to depth,
c) program stop,
d) rapid out, and
e) program stop.

The G87 Peck-Drill-with-Chip-Breaker canned cycle is the same as the G83 Peck Drilling canned cycle except that t rool etraction at each peck is only 0.050" (i.e., does not come out of the hole like the G83 command.
The G87 Peck-Drill-with-Chip-Breaker canned cycle will:
a) rapid down to clearance plane,
b) feed in 1st peck increment,
b) rapid up 0.050 to break chip,
