NOTE
1.
Circle
cutting
is
only
performed
in
the
XY
plane.
If
commanded
for
cutting
in
other
planes,
alarm
“361”

However,
if
the

ON,
the

In
circle
cutting
(G12, G13),
the tool radius is
compensated
for
irrespective
of G41

G42
(tool

specification.
G12
and
G13
must
be
commanded
in
the
G40
(tool

mode.
If
commanded
in
any
other
mode,
alarm
“182”
results.

Although
movements
in
“X
+
”
direction
are
explained
here,
movements
in
"X—”
direction
(symmetrical
to
Y-axis)
can
also
be
made
by
changing
the
signs
of
I,
J,
K,
and
D
accordingly.
In
the
example
in
Fig.
2.13.24,
all
I,
R,
and
(D)
are
negative.
Note however
that
cutting
in
the
direction
toward
Y-axis is
impossible.
5.
I,
J, K,
R,
Q,
and
L in
circle
cutting
are
effective
in
one
block
only.
Although
J
and
L
can
be
omitted,
"I"
must
always
be commanded.
If
all
are
omitted,
alarm
“362”
results.

the limits
are
