Return
to
R
point
The
tool
returns to
the
programmed
"R
point"
on
completion
of
canned
cycle.
NOTES:
•
In
principle,
program
G92
in
the
state
where
all
tool
offset
modes
are
cancelled.
•
When
the
power
is
turned
on,
the
current
posi¬
tion
of
the tool
is
set
as
absolute
zero
point
(0,
0, 0,
0+).
Make
sure
to
reprogram
absolute
coordinate
by
G92
before
executing
the
automa¬
tic
operation.
•
The
programmed
absolute
zero
point
is
not
af¬
fected
by
reset
operation.
Perform
any
of
the
following
operations
for
resetting
the
absolute
zero
point.

G98,

are
modal
G
codes
of
group
G. G98
(return
to
initial
point)
is
selected when
the
power
is turned
on.
These
G
codes
are
for
selecting
whether
to
desig¬
nate
the
feed
in
mm/min.
or
in
mm/rev.
prior
to
programming
the
F
code
for
feed,
in
the
case
where
the
control is
equipped
with
feed
per
revo-
lution+
function.
NOTE:
If
the
next
canned
cycles
are
continuously
programmed
after
return
to
R
point
on
connection
of
the
preceding
canned
cycles
instructions,
the
canned
cycles
are
executed
with
this
R
point
as
the
start
point.
In
general
when
drilling
many
holes,
program
G99
(R
point)
before
the
first
drilling
and
program
G98 before
the
final
drilling.
•
When
G94
*
is
programmed,
the
F
code
pro¬
grammed
thereafter
is
executed
in
mm/min.
(or
inch/min.i’,
deg/min.ÿ).
•
When
G9
5
*
is
programmed,
the
F
code
pro¬
grammed
thereafter
is executed
in
mm/rev.
(or
inch/rev.
+,
deg/rev.
+).
•
G94,
G95
are
modal
G
codes
of
F
group,
and
G94
is
selected
when the
power
is turned
on.
When
switching
between
G94
and
G95
is
made,
the
previously
programmed
F
code
is
cancel¬
led.
Therefore,
a
new
F
code
must
be
program¬
med.
