NOTE
—
O
For
a
hole-opening
cycle
to
be
executed
using
G70,
G71,
or
G72,
a
canned
cycle
where
L
=
0
(G73,
G74,
G76,
G77,
G81
to
G89)
must,
as a
rule,
be
commanded
in
the
preceding
block
as
shown
in
the
program
example
above.
By
definition
of
L
=
0,
the
canned
cycle
movement
is
not
exe¬
cuted
at
that
position
and
hole
machining
data
are
entered.
0
G70,
G71,
or
G72
and
the canned
cycle
G
code
can
be
commanded
in
the
same
block.
However,
a
canned
cycle
(G73, G83)
containing
I,
J,
or
K
commands
cannot
be
commanded
in
the
same
block.
When
using
G73
or
G83,
and
2-step
hole canned
cycle
(G18U
G182,
G185,
G186,
G187
or
G189)
be
sure
to
use
Q
or
command
I.J.or
K
in
the
previous
block
in
advance.
©
Because
G70,
G71.
or
G72
machining
is
completed
on
the last
hole,
if
the tool
is
to
be
moved
to
the
next
position,
it
is
necessary
for
the
G91
(incremental)
mode
to
calculate that
position.
G90
(absolute)
mode
is
more
convenient
because
it
is
not
a
necessary
calculation.
O
When
G70, G71,
or
G72
machining
is
completed,
the
system
remains
in
the canned
cycle
mode.
Attention
must
be
paid
to
the
program
in
the
next
block.
Generally,
it
is
necessary
to
cancel the mode
with
G80.
0
If
G70,
G71,
or
G72
is
commanded
in
nose
radius
compensation
(G41,
G42),
alarm
“182”
results.
0
G70,
G71,
and
G72
are
non-mod
al
G
codes.
0
G70,
G71,
and
G72
must
always
be
commanded
in
a
canned
cycle
mode
(otherwise,
alarm
"171”
results).
