PLANE
DESIGNATION
(Gl7,

The
plane
for
making
circular
interpolation
and
tool
radius
compensation
is
designated by
G
codes
G17/G18/G19.

However,
for
the
plane
for
making
circular
inter¬
polation,
address characters
X,

Z,'(a)ÿ',
1,
J and
K
take
priority
over
the
designation
made
by
G17-,
G18
and
G19.
The
latter
designation
is
valid
only
when the
interpolation
plane
is
not
de¬
termined due
to
omission
of
address characters
or
the
like.

The
axes
for
performing
circle
cutting,
helical
cutting
and
canned
cycles
are
designated
inde¬
pendently
those
of
stated
above.
The
move
command
in
each
axis
can
be
program¬
med
regardless
of
the
plane
designation by
G17/
G18/G19.
For
example,
if
G17

is
designated,
motion
is
on
Z
axis.
The
plane
for
making
tool
radius
compensation
by
command
G41 orG42
is
univocally
determined
by
G17,
G18
or
G19.
It
is
not
possible
to
desig¬
nate
compensation plane
including
the
fourth
axis.
The
XY
plane
(G17)
is
selected
when the
power
is
turned
on.

However,
it
is
not
possible
to
program
G25
in
the
last
block
of
the
program
to
be
copied.
An
input
error
occurs
in
this
case,
Program
copy
cannot
be
programmed
in
canned
cycle
modes
(G73,
G76,
G81
to
G89).
If
it
is
programmed,
an
input
error
occurs
because
P,

values
of
the canned
cycles
are
changed.
However,
canned

to

NOTES:
It
is
possible
to
program
a

com¬
mand
M99
in
the
program
to
be

That
is,
it
becomes
the
function
of
M99
in
the
main
program.
(See
program
example.)
The
precautions
for

the
same
as

of

Subprogram
Function.
G25
can
be
programmed
from
tape
or
memory,
but
it
is
necessary
to store
the
program
to
be
copied
in
memory-.
Exercise
care
so
that the
sequence
numbers
do
not
overlap.
G25
may
be
programmed
in
the
program
to
be
copied..
This is
called
multiple
program copy
and such
copy
is
possible
up
to
eighth
level.
