If
the
end
point
is
designated
in
the shaded
area,
no
alarm
condition
is
created,
but the
tool
keeps
on
moving
in
circle
endlessly. Especially
when
giving
tool
compensation,
etc.,
the
coordinates
of
the
end
point
and
the
center
must
be
accurate.
•
If
an
arc
with
a
center
angle
larger
than
180°
is
given
as a
circular
interpolation
through
radius
R
designation
by
mistakes,
the tool
path
will
be
as
shown
in
Fig.

.
•
When
designating
circular
interpolation
using
the
radius
R
command,
the
center
angle
cannot
exceed
180°.
If
a
radius
shorter than
half
the
distance
between the
start
and
end
points
is
de¬
signated,
this
constitutes
an
input
error.
•
With
a
circular
interpolation
by
radius
R
des¬
ignation,
if
one
or
both
end
point
coordinates
are
omitted,
the
tool
path
will
be
defined
on
the
plane
designated
by
the
plane
designation
codes.
•
With
all
circular
interpolation
blocks,
codes
related
to
arc
center
such
as
I,
J,
K
and
R
can¬
not
be
omitted.
If
no
radius
or
arc
center
is
specified,
this
is
interpreted
as
a
zero
value.

The
exact-stop-check
is the
function
of
stopping
the
advance
to
the
next
block
while
discharging
the
servo-lag
pulses.
Corners
are
rounded
to
a
certain
extent
in
normal
cutting
feed
because
of
smooth
connection between
blocks
in
normal
cut¬
ting
feed,
but
a
sharp
corner
can
be
cut
if
an
ex¬
act-stop-check
or
a
dwell
is
used.
